Apache Solr Release Notes Introduction ------------ Apache Solr is an open source enterprise search server based on the Apache Lucene Java search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, and a web administration interface. See http://lucene.apache.org/solr for more information. ================== 5.2.1 ================== Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release Versions of Major Components --------------------- Apache Tika 1.7 Carrot2 3.9.0 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.6 Jetty 9.2.10.v20150310 Detailed Change List ---------------------- Bug Fixes ---------------------- * SOLR-7588: Fix javascript bug introduced by SOLR-7409 that breaks the dataimport screen in the admin UI. (Bill Bell via Shawn Heisey) * SOLR-7616: Faceting on a numeric field with a unique() subfacet function on another numeric field can result in incorrect results or an exception. (yonik) * SOLR-7518: New Facet Module should respect shards.tolerant and process all non-failing shards instead of throwing an exception. (yonik) * SOLR-7574: A request with a json content type but no body caused a null pointer exception (yonik) * SOLR-7512: SolrOutputFormat creates an invalid solr.xml in the solr home zip for MapReduceIndexerTool. (Mark Miller, Adam McElwee) * SOLR-7638: Fix new (Angular-based) admin UI Cloud pane (Upayavira via ehatcher) * SOLR-7655: The DefaultSolrHighlighter since 5.0 was determining if payloads were present in a way that was slow, especially when lots of fields were highlighted. It's now fast. (David Smiley) * SOLR-7493: Requests aren't distributed evenly if the collection isn't present locally. (Jeff Wartes, shalin) Other Changes ---------------------- * SOLR-7623: Fix regression from SOLR-7484 that made it impossible to override SolrDispatchFilter#execute() and SolrDispatchFilter#sendError(). You can now override these functions in HttpSolrCall. (ryan) * SOLR-7648: Expose remote IP and Host via the AuthorizationContext to be used by the authorization plugin. (Ishan Chattopadhyaya via Anshum Gupta) ================== 5.2.0 ================== Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release Versions of Major Components --------------------- Apache Tika 1.7 Carrot2 3.9.0 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.6 Jetty 9.2.10.v20150310 Upgrading from Solr 5.1 ----------------------- * A bug was introduced in Solr 4.10 that caused index time document boosts to trigger excessive field boosts in multivalued fields -- the result being that some field norms might be excessively large. This bug has now been fixed, but users of document boosts are strongly encouraged to re-index. See SOLR-7335 for more details. * The Slice and Replica classes have been changed to use State enums instead of string constants to track the respective stats. Advanced users with client code manipulating these objects will need to update their code accordingly. See SOLR-7325 and SOLR-7336 for more info. * Solr has internally been upgraded to use Jetty 9. See SOLR-4839 for full details, but there are a few key details all Solr users should know when upgrading: - It is no longer possible to run "java -jar start.jar" from inside the server directory. The bin/solr script is the only supported way to run Solr. This is necessary to support HTTP and HTTPS modules in Jetty which can be selectively enabled by the bin/solr scripts. In case you have a pressing need to run solr the old way, you can run "java -jar start.jar --module=http" to get the same behavior as before. - The way SSL support is configured has been changed. Before this release, the SOLR_SSL_OPTS property configured in solr.in.sh (linux/mac) or solr.in.cmd (windows) was used to enable/disable SSL but starting in 5.2.0, new properties named as SOLR_SSL_KEY_STORE, SOLR_SSL_KEY_STORE_PASSWORD, SOLR_SSL_TRUST_STORE, SOLR_SSL_TRUST_STORE_PASSWORD, SOLR_SSL_NEED_CLIENT_AUTH and SOLR_SSL_WANT_CLIENT_AUTH have been introduced. The bin/solr scripts configure the SOLR_SSL_OPTS property automatically based on the above new properties. You should *not* configure the SOLR_SSL_OPTS property directly inside solr.in.{sh,cmd}. - Support for SOLR_SSL_PORT property has been removed. Instead use the regular SOLR_PORT property or specify the port while invoking the bin/solr script using the "-p" switch. - Furthermore, it is now possible to configure the HTTP client with different SSL properties than the ones used for Jetty using the same files. - Please refer to the "Enabling SSL" section in the Solr Reference Guide for complete details. * Support for pathPrefix has been completely removed from Solr. Since 5.0, Solr no longer officially supports being run as a webapp but allowed users to play around with the web.xml to have a path prefix. That would no longer be true. See SOLR-7500 for more info. * The package structure under org.apache.solr.client.solrj.io has been changed to support the Streaming Expression Language (SOLR-7377). Any code written with the 5.1 Streaming API will have to be updated to reflect these changes. * Merge Policy's "noCFSRatio" is no longer set based on element in the indexConfig section of solrconfig.xml. This means that Solr will start using Lucene's default for MP "noCFSRatio", with this new default Solr will decide if a segment should use cfs or not based on the size of the segment in relation the size of the complete index. For TieredMergePolicy for example (current default), segments will use cfs if they are less than 10% of the index, otherwise cfs is disabled. Old values for this setting (1.0 for useCompoundFile=true and 0.0 for useCompoundFile=false) as well as any other value can be set inside the element in solrconfig.xml. will only apply to newly created segments. See SOLR-7463. Detailed Change List ---------------------- New Features ---------------------- * SOLR-6637: Restore a Solr core from a backed up index. Restore API Example - http://localhost:8983/solr/techproducts/replication?command=restore&name=backup_name Restore Status API Example - http://localhost:8983/solr/techproducts/replication?command=restorestatus (Varun Thacker, noble, shalin) * SOLR-7241, SOLR-7263, SOLR-7279, SOLR-7300, SOLR-7396, SOLR-7397, SOLR-7492: Admin UI - Refactoring using AngularJS.

(yonik, shalin) * SOLR-7376: Return raw XML or JSON (in the appropriate writer) using DocumentTransformers. ?fl=id,name,json_s:[json],xml_s:[xml] (ryan) * SOLR-7422: Optional flatter form for the JSON Facet API via a "type" parameter: top_authors : { type:terms, field:author, limit:5 } is equivalent to top_authors : { terms : { field:author, limit:5 } } (yonik) * SOLR-7176: zkcli script can perfrom the CLUSTERPROP command without a running Solr cluster (Hrishikesh Gadre, Per Steffensen, Noble Paul) * SOLR-7417: JSON Facet API - unique() is now implemented for numeric and date fields. (yonik) * SOLR-7406: Add a new "facet.range.method" parameter to let users choose how to do range faceting between an implementation based on filters (previous algorithm, using "facet.range.method=filter") or DocValues ("facet.range.method=dv"). Input parameters and output of both methods are the same. (Tomás Fernández Löbbe) * SOLR-7473: Facet Module (Json Facet API) range faceting now supports the "mincount" parameter in range facets to supress buckets less than that count. The default for "mincount" remains 0 for range faceting. Example: prices:{ type:range, field:price, mincount:1, start:0, end:100, gap:10 } (yonik) * SOLR-7437: Make HDFS transaction log replication factor configurable. (Mark Miller) * SOLR-7477: Multi-select faceting support for the Facet Module via the "excludeTags" parameter which disregards any matching tagged filters for that facet. Example: & q=shoes & fq={!tag=COLOR}color:blue & json.facet={ colors:{type:terms, field:color, excludeTags=COLOR} } (yonik) * SOLR-7231: DIH-TikaEntityprocessor, create lat-lon field from Metadata (Tim Allison via Noble Paul) * SOLR-6220: Rule Based Replica Assignment during collection, shard creation and replica creation (Noble Paul) * SOLR-6968: New 'cardinality' option for stats.field, uses HyperLogLog to efficiently estimate the cardinality of a field w/bounded RAM. (hossman) * SOLR-4392: Make it possible to specify AES encrypted password in dataconfig.xml (Noble Paul) * SOLR-7461: stats.field now supports individual local params for 'countDistinct' and 'distinctValues'. 'calcdistinct' is still supported as an alias for both options (hossman) * SOLR-7522: Facet Module - Implement field/terms faceting over single-valued numeric fields. (yonik) * SOLR-7275: Authorization framework for Solr. It defines an interface and a mechanism to create, load, and use an Authorization plugin. (Noble Paul, Ishan Chattopadhyaya, Anshum Gupta) * SOLR-7377: Solr Streaming Expressions (Dennis Gove, Joel Bernstein, Steven Bower) * SOLR-7553: Facet Analytics Module: new "hll" function that uses HyperLogLog to calculate distributed cardinality. The original "unique" function is still available. Example: json.facet={ numProducts : "hll(product_id)" } (yonik) * SOLR-7546: bin/post (and SimplePostTool in -Dauto=yes mode) now sends rather than skips files without a known content type, as "application/octet-stream", provided it still is in the allowed filetypes setting. (ehatcher) * SOLR-7274: Pluggable authentication module in Solr. This defines an interface and a mechanism to create, load, and use an Authentication plugin. (Noble Paul, Ishan Chattopadhyaya, Gregory Chanan, Anshum Gupta) * SOLR-7379: (experimental) New spatial RptWithGeometrySpatialField, based on CompositeSpatialStrategy, which blends RPT indexes for speed with serialized geometry for accuracy. Includes a Lucene segment based in-memory shape cache. (David Smiley) * SOLR-7465, SOLR-7610: New file indexing example, under example/files. (Esther Quansah, Erik Hatcher) * SOLR-7468: Kerberos authenticaion plugin for Solr. This would allow running a Kerberized Solr. (Noble Paul, Ishan Chattopadhyaya, Gregory Chanan, Anshum Gupta) Bug Fixes ---------------------- * SOLR-6709: Fix QueryResponse to deal with the "expanded" section when using the XMLResponseParser (Varun Thacker, Joel Bernstein) * SOLR-7066: autoAddReplicas feature has bug when selecting replacement nodes. (Mark Miller) * SOLR-7370: FSHDFSUtils#recoverFileLease tries to recover the lease every one second after the first four second wait. (Mark Miller) * SOLR-7369: AngularJS UI insufficient URLDecoding in cloud/tree view (janhoy) * SOLR-7380: SearchHandler should not try to load runtime components in inform() (Noble Paul) * SOLR-7385: The clusterstatus API now returns the config set used to create a collection inside a 'configName' key. (Shai Erera, shalin) * SOLR-7401: Fixed a NullPointerException when concurrently creating and deleting collections, while accessing other collections. (Shai Erera) * SOLR-7412: Fixed range.facet.other parameter for distributed requests. (Will Miller, Tomás Fernándes Löbbe) * SOLR-6087: SolrIndexSearcher makes no DelegatingCollector.finish() call when IndexSearcher throws an expected exception. (Christine Poerschke via shalin) * SOLR-7420: Overseer stats are not reset on loss of ZK connection. (Jessica Cheng, shalin) * SOLR-7392: Fix SOLR_JAVA_MEM and SOLR_OPTS customizations in solr.in.sh being ignored (Ramkumar Aiyengar, Ere Maijala) * SOLR-7426: SolrConfig#getConfigOverlay does not clean up it's resources. (Mark Miller) * SOLR-6665: ZkController.publishAndWaitForDownStates can return before all local cores are marked as 'down' if multiple replicas with the same core name exist in the cluster. (shalin) * SOLR-7418: Check and raise a SolrException instead of an NPE when an invalid doc id is sent to the MLTQParser. (Anshum Gupta) * SOLR-7443: Implemented range faceting over date fields in the new facet module (JSON Facet API). (yonik) * SOLR-7440: DebugComponent does not return the right requestPurpose for pivot facet refinements. (shalin) * SOLR-7408: Listeners set by SolrCores on config directories in ZK could be removed if collections are created/deleted in paralle against the same config set. (Shai Erera, Anshum Gupta) * SOLR-7450: Fix edge case which could cause `bin/solr stop` to hang forever (Ramkumar Aiyengar) * SOLR-7157: initParams must support tags other than appends, defaults and, invariants (Noble Paul) * SOLR-7387: Facet Module - distributed search didn't work when sorting terms facet by min, max, avg, or unique functions. (yonik) * SOLR-7469: Fix check-licenses to correctly detect if start.jar.sha1 is incorrect (hossman) * SOLR-7449: solr/server/etc/jetty-https-ssl.xml hard codes the key store file and password rather than pulling them from the sysprops defined in solr/bin/solr.in.{sh,cmd} * SOLR-7470: Fix sample data to eliminate file order dependency for successful indexing, also fixed SolrCloudExampleTest to help catch this in the future. (hossman) * SOLR-7478: UpdateLog#close shuts down it's executor with interrupts before running it's close logic, possibly preventing a clean close. (Mark Miller) * SOLR-7494: Facet Module - unique() facet function was wildly inaccurate for high cardinality fields. (Andy Crossen, yonik) * SOLR-7502: start script should not try to create configset for .system collection (Noble Paul) * SOLR-7514: SolrClient.getByIds fails with ClassCastException (Tom Farnworth, Ramkumar Aiyengar) * SOLR-7531: config API shows a few keys merged together (Noble Paul) * SOLR-7542: Schema API: Can't remove single dynamic copy field directive (Steve Rowe) * SOLR-7472: SortingResponseWriter does not log fl parameters that don't exist. (Joel Bernstein) * SOLR-7545: Honour SOLR_HOST parameter with bin/solr{,.cmd} (Ishan Chattopadhyaya via Ramkumar Aiyengar) * SOLR-7503: Recovery after ZK session expiration should happen in parallel for all cores using the thread-pool managed by ZkContainer instead of a single thread. (Jessica Cheng Mallet, Timothy Potter, shalin, Mark Miller) * SOLR-7335: Fix doc boosts to no longer be multiplied in each field value in multivalued fields that are not used in copyFields (Shingo Sasaki via hossman) * SOLR-7585: Fix NoSuchElementException in LFUCache resulting from heavy writes making concurrent put() calls. (Maciej Zasada via Shawn Heisey) * SOLR-7587: Seeding bucket versions from index when the firstSearcher event fires has a race condition that leads to an infinite wait on VersionInfo's ReentrantReadWriteLock because the read-lock acquired during a commit cannot be upgraded to a write-lock needed to block updates; solution is to move the call out of the firstSearcher event path and into the SolrCore constructor. (Timothy Potter) * SOLR-7625: Ensure that the max value for seeding version buckets is updated after recovery even if the UpdateLog is not replayed. (Timothy Potter) * SOLR-7610: Fix VelocityResponseWriter's $resource.locale to accurately report locale in use. (ehatcher) * SOLR-7614: Distributed pivot facet refinement was broken due to a single correlation counter used across multiple requests as if it was private to each request. (yonik) Optimizations ---------------------- * SOLR-7324: IndexFetcher does not need to call isIndexStale if full copy is already needed (Stephan Lagraulet via Varun Thacker) * SOLR-7547: Short circuit SolrDisptachFilter for static content request. Right now it creates a new HttpSolrCall object and tries to process it. (Anshum Gupta) * SOLR-7333: Make the poll queue time a leader uses when distributing updates to replicas configurable and use knowledge that a batch is being processed to poll efficiently. (Timothy Potter) * SOLR-7332: Initialize the highest value for all version buckets with the max value from the index or recent updates to avoid unnecessary lookups to the index to check for reordered updates when processing new documents. (Timothy Potter, yonik) * SOLR-5855: DefaultSolrHighlighter now re-uses the document's term vectors instance when highlighting more than one field. Applies to the standard and FVH highlighters. (David Smiley, Daniel Debray) Other Changes ---------------------- * SOLR-6865: Upgrade HttpClient to 4.4.1 (Shawn Heisey) * SOLR-7358: TestRestoreCore fails in Windows (Ishan Chattopadhyaya via Varun Thacker) * SOLR-7371: Make DocSet implement Accountable to estimate memory usage. (yonik, shalin) * SOLR-7381: Improve logging by adding node name in MDC in SolrCloud mode and adding MDC to all thread pools. A new MDCAwareThreadPoolExecutor is introduced and usages of Executors#newFixedThreadPool, #newSingleThreadExecutor, #newCachedThreadPool as well as ThreadPoolExecutor directly is now forbidden in Solr. MDC keys are now exposed in thread names automatically so that a thread dump can give hints on what the thread was doing. Uncaught exceptions thrown by tasks in the pool are logged along with submitter's stack trace. (shalin) * SOLR-7384: Fix spurious failures in FullSolrCloudDistribCmdsTest. (shalin) * SOLR-6692: Default highlighter changes: - hl.maxAnalyzedChars now applies cumulatively on a multi-valied field. - fragment ranking on a multi-valued field should be more relevant. - hl.usePhraseHighlighter is now toggleable on a per-field basis. - Much more extensible (get values from another source; return snippet scores and offsets). - When using hl.maxMultiValuedToMatch with hl.preserveMulti, only count matched snippets. (David Smiley) * SOLR-6886: Removed redundant size check and added missing calls to DelegatingCollection.finish inside Grouping code. (Christine Poerschke via shalin) * SOLR-7421: RecoveryAfterSoftCommitTest fails frequently on Jenkins due to full index replication taking longer than 30 seconds. (Timothy Potter, shalin) * SOLR-7081: Add new test case to test if create/delete/re-create collections work. (Christine Poerschke via Ramkumar Aiyengar) * SOLR-7467: Upgrade t-digest to 3.1 (hossman) * SOLR-7471: Stop requiring docValues for interval faceting (Tomás Fernández Löbbe) * SOLR-7391: Use a time based expiration cache for one off HDFS FileSystem instances. (Mark Miller) * SOLR-5213: Log when shard splitting unexpectedly leads to documents going to no or multiple shards (Christine Poerschke, Ramkumar Aiyengar) * SOLR-4839: Upgrade Jetty to 9.2.10.v20150310 and restlet-jee to 2.3.0 (Bill Bell, Timothy Potter, Uwe Schindler, Mark Miller, Steve Rowe, Steve Davids, shalin) * SOLR-7425: Improve MDC based logging format. (Mark Miller) * SOLR-7457: Make DirectoryFactory publishing MBeanInfo extensible. (Mike Drob via Mark Miller) * SOLR-7325: Slice.getState() now returns a State enum instead of a String. This helps clarify the states a Slice can be in, as well comparing the state of a Slice. (Shai Erera) * SOLR-7336: Added Replica.getState() and removed ZkStateReader state-related constants. You should use Replica.State to compare a replica's state. (Shai Erera) * SOLR-7487: Fix check-example-lucene-match-version Ant task to check luceneMatchVersion in solr/server/solr/configsets instead of example and harden error checking / validation logic. (hossman, Timothy Potter) * SOLR-7409: When there are multiple dataimport handlers defined, the admin UI was listing them in a random order. Now they are sorted in a natural order that handles numbers properly. (Jellyfrog via Shawn Heisey) * SOLR-7484: Refactor SolrDispatchFilter to extract all Solr specific implementation detail to HttpSolrCall and also extract methods from within the current SDF.doFilter(..) logic making things easier to manage. HttpSolrCall converts the processing to a 3-step process i.e. Construct, Init, and Call so the context of the request would be available after Init and before the actual call operation. (Anshum Gupta, Noble Paul) * SOLR-6878: Allow symmetric lists of synonyms to be added using the managed synonym REST API to support legacy expand=true type mappings; previously the API only allowed adding explicit mappings, with this feature you can now add a list and have the mappings expanded when the update is applied (Timothy Potter, Vitaliy Zhovtyuk, hossman) * SOLR-7102: bin/solr should activate cloud mode if ZK_HOST is set (Timothy Potter) * SOLR-7500: Remove pathPrefix from SolrDispatchFilter as Solr no longer runs as a part of a bigger webapp. (Anshum Gupta) * SOLR-7243: CloudSolrClient was always returning SERVER_ERROR for exceptions, even when a more relevant ErrorCode was available, via SolrException. Now the actual ErrorCode is used when available. (Hrishikesh Gadre via Shawn Heisey) * SOLR-7544: CollectionsHandler refactored to be more modular (Noble Paul) * SOLR-7532: Removed occurrences of the unused 'commitIntervalLowerBound' property for updateHandler elements from Solr configuration. (Marius Grama via shalin) * SOLR-7541: Removed CollectionsHandler#createNodeIfNotExists. All calls made to this method now call ZkCmdExecutor#ensureExists as they were doing the same thing. Also ZkCmdExecutor#ensureExists now respects the CreateMode passed to it. (Varun Thacker) * SOLR-6820: Make the number of version buckets used by the UpdateLog configurable as increasing beyond the default 256 has been shown to help with high volume indexing performance in SolrCloud; helps overcome a limitation where Lucene uses the request thread to perform expensive index housekeeping work. (Mark Miller, yonik, Timothy Potter) * SOLR-7463: Stop forcing MergePolicy's "NoCFSRatio" based on the IWC "useCompoundFile" configuration (Tomás Fernández Löbbe) * SOLR-7582: Allow auto-commit to be set with system properties in data_driven_schema_configs and enable auto soft-commits for the bin/solr -e cloud example using the Config API. (Timothy Potter) * SOLR-7183: Fix Locale blacklisting for Minikdc based tests.

NOTE: Solr 5.0 only supports creating and removing SolrCloud collections through the collections API, unlike previous versions. While not using the collections API may still work in 5.0, it is unsupported, not recommended, and the behavior will change in a 5.x release. Versions of Major Components --------------------- Apache Tika 1.7 Carrot2 3.9.0 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.6 Jetty 8.1.10.v20130312 Upgrading from Solr 4.x ---------------------- * Apache Solr has no support for Lucene/Solr 3.x and earlier indexes anymore. Be sure to run Lucene's IndexUpgrader on the previous 4.10 version if you might still have old segments in your index. Alternatively fully optimize your index with Solr 4.10 to make sure it consists only of one up-to-date index segment. * The "file" attribute of infoStream in solrconfig.xml is removed. Control this via your logging configuration (org.apache.solr.update.LoggingInfoStream) instead. * UniqFieldsUpdateProcessorFactory no longer supports the init param style that was deprecated in Solr 4.5. If you are still using this syntax, update your configs to use instead. See SOLR-4249 for more details. * The following legacy numeric and date field types, deprecated in Solr 4.8, are no longer supported: BCDIntField, BCDLongField, BCDStrField, IntField, LongField, FloatField, DoubleField, SortableIntField, SortableLongField, SortableFloatField, SortableDoubleField, and DateField. Convert these types in your schema to the corresponding Trie-based field type and then re-index. See SOLR-5936 for more information. * getAnalyzer() in IndexSchema and FieldType that was deprecated in Solr 4.9 has been removed. Use getIndexAnalyzer() instead. See SOLR-6022 for more information. * The spellcheck response format has changed, affecting xml and json clients. In particular, the "correctlySpelled" and "collations" subsections have been moved outside the "suggestions" subsection, and now are directly under "spellcheck". See SOLR-3029 for more information. * The CollectionsAPI SolrJ calls createCollection(), reloadCollection(), deleteCollection(), requestStatus(), createShard(), splitShard(), deleteShard(), createAlias() and deleteAlias() which were deprecated in 4.11 have been removed. The new usage involves a builder style construction of the call. * The OVERSEERSTATUS API returns new key names for operations such as "create" for "createcollection", "delete" for "removecollection" and "deleteshard" for "removeshard". * If you have been using the /update/json/docs to index documents, SOLR-6617 introduces backward incompatible change. the key names created are fully qualified paths of keys . If you need the old functionality back , please add an extra parameter f=/** example: /update/json/docs?f=/** * Bugs fixed in several ValueSource functions may result in different behavior in situations where some documents do not have values for fields wrapped in other value sources. Users who want to preserve the previous behavior may need to wrap fields in the "def()" function. Example: changing "fl=sum(fieldA,fieldB)" to "fl=sum(def(fieldA,0.0),def(fieldB,0.0))". See LUCENE-5961 for more details. * AdminHandlers is deprecated, /admin/* are implicitly defined, /get, /replication and handlers are also implicitly registered (refer to SOLR-6792) * The "termIndexInterval" option in solrconfig.xml has been a No-Op in the default codec since Solr 4.0, and has been removed completely in 5.0. If you get an "Illegal parameter 'termIndexInterval'" error when upgrading, you can safely remove this option from your configs. If you have a strong need to configure this, you must explicitly configure your schema with a custom codec. See SOLR-6560 and for more details. * The "checkIntegrityAtMerge" option in solrconfig.xml is now a No-Op and should be removed from any solrconfig.xml files -- these integrity checks are now done automatically at a very low level during the segment merging process. See SOLR-6834 for more details. * SimplePostTool (post.jar) no longer defaults to collection1, making either of core/collection name or update URL mandatory. An existing call without an explicit update URL needs to now have the core/collection name passed as "-Dc=" e.g.: java -jar -Dc= post.jar *.xml (new call with collection name) See SOLR-6852 for more details. * Relative paths specified in the solr.xml coreRootDirectory parameter for core discovery are now resolved relative to SOLR_HOME, rather than cwd. See SOLR-6718. * SolrServer and associated classes have been deprecated. Applications using SolrJ should use the equivalent SolrClient classes instead. * Spatial fields originating from Solr 4 (e.g. SpatialRecursivePrefixTreeFieldType, BBoxField) have the 'units' attribute deprecated, now replaced with 'distanceUnits'. If you change it to a unit other than 'degrees' (or if you don't specify it, which will default to kilometers if geo=true), then be sure to update maxDistErr as it's in those units. If you keep units=degrees then it should be backwards compatible but you'll get a deprecation warning on startup. See SOLR-6797. * The configuration in solrconfig.xml has been discontinued and should be removed from solrconfig.xml. Solr defaults to using NRT searchers regardless of the value in configuration and a warning is logged on startup if the solrconfig.xml has specified. * There was an old spatial syntax to specify a circle using Circle(x,y d=...) which should be replaced with simply using {!geofilt} (if you can) or BUFFER(POINT(x y),d). Likewise a rect syntax comprised of minX minY maxX maxY that should now be replaced with ENVELOPE(minX, maxX, maxY, minY). * Due to changes in the underlying commons-codec package, users of the BeiderMorseFilterFactory will need to rebuild their indexes after upgrading. See LUCENE-6058 for more details. * CachedSqlEntityProcessor has been removed, use SqlEntityProcessor with the cacheImpl parameter. * HttpDataSource has been removed, use URLDataSource instead. * LegacyHTMLStripCharFilter has been removed * CoreAdminRequest.persist() call has been removed. All changes made via CoreAdmin are persistent. * SpellCheckResponse.getSuggestions() and getSuggestionFrequencies() have been removed, use getAlternatives() and getAlternativeFrequencies() instead. * SolrQuery deprecated methods have been removed: - setMissing() is now setFacetMissing() - getFacetSort() is now getFacetSortString() - setFacetSort(boolean) should instead use setFacetSort(String) with FacetParams.FACET_SORT_COUNT or FacetParams.FACET_SORT_INDEX - setSortField(String, ORDER) should use setSort(SortClause) - addSortField(String, ORDER) should use addSort(SortClause) - removeSortField(String, ORDER) should use removeSort(SortClause) - getSortFields() should use getSorts() - set/getQueryType() should use set/getRequestHandler() * ClientUtil deprecated date methods have been removed, use DateUtil instead * FacetParams.FacetDateOther has been removed, use FacetRangeOther * ShardParams.SHARD_KEYS has been removed, use ShardParams._ROUTE_ * The 'old-style' solr.xml format is no longer supported, and cores must be defined using core.properties files. See https://cwiki.apache.org/confluence/display/solr/Format+of+solr.xml Detailed Change List ---------------------- New Features ---------------------- * SOLR-6103: Added DateRangeField for indexing date ranges, especially multi-valued ones.

It is applied to nearly all distance measurements involving the field: maxDistErr, distErr, d, geodist, score=distance|area|area2d. score now accepts these units as well. It does NOT affect distances embedded in WKT strings like BUFFER(POINT(200 10),0.2)). (Ishan Chattopadhyaya, David Smiley) * SOLR-6766: Expose HdfsDirectoryFactory Block Cache statistics via JMX.

As of Solr 4.10, TrieDateField omits norms by default (see SOLR-6211). * Creating a SolrCore via CoreContainer.create() no longer requires an additional call to CoreContainer.register() to make it available to clients (see SOLR-6170). * CoreContainer.remove() has been removed. You should now use CoreContainer.unload() to delete a SolrCore (see SOLR-6232). * solr.xml parsing has been improved to better account for the expected data types of various options. As part of this fix, additional error checking has also been added to provide errors in the event of duplicated options, or unknown option names that may indicate a typo. Users who have modified their solr.xml in the past and now upgrade may get errors on startup if they have typos or unexpected options specified in their solr.xml file.

(Karl Wright, Mark Miller) * SOLR-5349: CloudSolrServer - ZK timeout arguments passed to ZkStateReader are flipped. (Ricardo Merizalde via shalin) * SOLR-5330: facet.method=fcs on single values fields could sometimes result in incorrect facet labels. (Michael Froh, yonik) Other Changes ---------------------- * SOLR-5323: Disable ClusteringComponent by default in collection1 example. The solr.clustering.enabled system property needs to be set to 'true' to enable the clustering contrib (reverts SOLR-4708). (Dawid Weiss) ================== 4.5.0 ================== Versions of Major Components --------------------- Apache Tika 1.4 Carrot2 3.8.0 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.5 Upgrading from Solr 4.4.0 ---------------------- * XML configuration parsing is now more strict about situations where a single setting is allowed but multiple values are found. In the past, one value would be chosen arbitrarily and silently. Starting with 4.5, configuration parsing will fail with an error in situations like this. If you see error messages such as "solrconfig.xml contains more than one value for config path: XXXXX" or "Found Z configuration sections when at most 1 is allowed matching expression: XXXXX" check your solrconfig.xml file for multiple occurrences of XXXXX and delete the ones that you do not wish to use. See SOLR-4953 & SOLR-5108 for more details. * In the past, schema.xml parsing would silently ignore "default" or "required" options specified on declarations. Beginning with 4.5, attempting to do configured these on a dynamic field will cause an init error. If you encounter one of these errors when upgrading an existing schema.xml, you can safely remove these attributes, regardless of their value, from your config and Solr will continue to behave exactly as it did in previous versions. See SOLR-5227 for more details. * The UniqFieldsUpdateProcessorFactory has been improved to support all of the FieldMutatingUpdateProcessorFactory selector options. The init param option is now deprecated and should be replaced with the more standard . See SOLR-4249 for more details. * UpdateRequestExt has been removed as part of SOLR-4816. You should use UpdateRequest instead. * CloudSolrServer can now use multiple threads to add documents by default. This is a small change in runtime semantics when using the bulk add method - you will still end up with the same exception on a failure, but some documents beyond the one that failed may have made it in. To get the old, single threaded behavior, set parallel updates to false on the CloudSolrServer instance. Detailed Change List ---------------------- New Features ---------------------- * SOLR-5219: Rewritten selection of the default search and document clustering algorithms. (Dawid Weiss) * SOLR-5202: Support easier overrides of Carrot2 clustering attributes via XML data sets exported from the Workbench. (Dawid Weiss) * SOLR-5126: Update Carrot2 clustering to version 3.8.0, update Morfologik to version 1.7.1 (Dawid Weiss) * SOLR-2345: Enhanced geodist() to work with an RPT field, provided that the field is referenced via 'sfield' and the query point is constant. (David Smiley) * SOLR-5082: The encoding of URL-encoded query parameters can be changed with the "ie" (input encoding) parameter, e.g. "select?q=m%FCller&ie=ISO-8859-1". The default is UTF-8. To change the encoding of POSTed content, use the "Content-Type" HTTP header. (Uwe Schindler, Shawn Heisey) * SOLR-4221: Custom sharding (Noble Paul) * SOLR-4808: Persist and use router,replicationFactor and maxShardsPerNode at Collection and Shard level (Noble Paul, Shalin Mangar) * SOLR-5006: CREATESHARD command for 'implicit' shards (Noble Paul) * SOLR-5017: Allow sharding based on the value of a field (Noble Paul) * SOLR-4222: create custom sharded collection via collections API (Noble Paul) * SOLR-4718: Allow solr.xml to be stored in ZooKeeper. (Mark Miller, Erick Erickson) * SOLR-5156: Enhance ZkCLI to allow uploading of arbitrary files to ZK. (Erick Erickson) * SOLR-5165: Single-valued docValues fields no longer require a default value. Additionally they work with sortMissingFirst, sortMissingLast, facet.missing, exists() in function queries, etc. (Robert Muir) * SOLR-5182: Add NoOpRegenerator, a regenerator for custom per-segment caches where items are preserved across commits. (Robert Muir) * SOLR-4249: UniqFieldsUpdateProcessorFactory now extends FieldMutatingUpdateProcessorFactory and supports all of its selector options. Use of the "fields" init param is now deprecated in favor of "fieldName" (hossman) * SOLR-2548: Allow multiple threads to be specified for faceting. When threading, one can specify facet.threads to parallelize loading the uninverted fields. In at least one extreme case this reduced warmup time from 20 seconds to 3 seconds. (Janne Majaranta, Gun Akkor via Erick Erickson, David Smiley) * SOLR-4816: CloudSolrServer can now route updates locally and no longer relies on inter-node update forwarding. (Joel Bernstein, Shikhar Bhushan, Stephen Riesenberg, Mark Miller) * SOLR-3249: Allow CloudSolrServer and SolrCmdDistributor to use JavaBin. (Mark Miller) Bug Fixes ---------------------- * SOLR-3633: web UI reports an error if CoreAdminHandler says there are no SolrCores (steffkes) * SOLR-4489: SpellCheckComponent can throw StringIndexOutOfBoundsException when generating collations involving multiple word-break corrections. (James Dyer) * SOLR-5087 - CoreAdminHandler.handleMergeAction generating NullPointerException (Patrick Hunt via Erick Erickson) * SOLR-5107: Fixed NPE when using numTerms=0 in LukeRequestHandler (Ahmet Arslan, hossman) * SOLR-4679, SOLR-4908, SOLR-5124: Text extracted from HTML or PDF files using Solr Cell was missing ignorable whitespace, which is inserted by TIKA for convenience to support plain text extraction without using the HTML elements. This bug resulted in glued words. (hossman, Uwe Schindler) * SOLR-5121: zkcli usage help for makepath doesn't match actual command. (Daniel Collins via Mark Miller) * SOLR-5119: Managed schema problems after adding fields via Schema Rest API. (Nils Kübler, Steve Rowe) * SOLR-5133: HdfsUpdateLog can fail to close a FileSystem instance if init is called more than once. (Mark Miller) * SOLR-5135: Harden Collection API deletion of /collections/$collection ZooKeeper node. (Mark Miller) * SOLR-4764: When using NRT, just init the first reader from IndexWriter. (Robert Muir, Mark Miller) * SOLR-5122: Fixed bug in spellcheck.collateMaxCollectDocs. Eliminates risk of divide by zero, and makes estimated hit counts meaningful in non-optimized indexes. (hossman) * SOLR-3936: Fixed QueryElevationComponent sorting when used with Grouping (Michael Garski via hossman) * SOLR-5171: SOLR Admin gui works in IE9, breaks in IE10. (Joseph L Howard via steffkes) * SOLR-5174: Admin UI - Query View doesn't highlight (json) Result if it contains HTML Tags (steffkes) * SOLR-4817 Solr should not fall back to the back compat built in solr.xml in SolrCloud mode (Erick Erickson) * SOLR-5112: Show full message in Admin UI Logging View (Matthew Keeney via steffkes) * SOLR-5190: SolrEntityProcessor substitutes variables only once in child entities (Harsh Chawla, shalin) * SOLR-3852: Fixed ZookeeperInfoServlet so that the SolrCloud Admin UI pages will work even if ZK contains nodes with data which are not utf8 text. (hossman) * SOLR-5206: Fixed OpenExchangeRatesOrgProvider to use refreshInterval correctly (Catalin, hossman) * SOLR-5215: Fix possibility of deadlock in ZooKeeper ConnectionManager. (Mark Miller, Ricardo Merizalde) * SOLR-4909: Use DirectoryReader.openIfChanged in non-NRT mode. (Michael Garski via Robert Muir) * SOLR-5227: Correctly fail schema initialization if a dynamicField is configured to be required, or have a default value. (hossman) * SOLR-5231: Fixed a bug with the behavior of BoolField that caused documents w/o a value for the field to act as if the value were true in functions if no other documents in the same index segment had a value of true. (Robert Muir, hossman, yonik) * SOLR-5233: The "deleteshard" collections API doesn't wait for cluster state to update, can fail if some nodes of the deleted shard were down and had incorrect logging. (Christine Poerschke, shalin) * SOLR-5150: HdfsIndexInput may not fully read requested bytes. (Mark Miller, Patrick Hunt) * SOLR-5240: All solr cores will now be loaded in parallel (as opposed to a fixed number) in zookeeper mode to avoid deadlocks due to replicas waiting for other replicas to come up. (yonik) * SOLR-5243: Killing a shard in one collection can result in leader election in a different collection if they share the same coreNodeName. (yonik, Mark Miller) * SOLR-5281: IndexSchema log message was printing '[null]' instead of '[]' (Jun Ohtani via Steve Rowe) * SOLR-5279: Implicit properties don't seem to exist on core RELOAD (elyograg, hossman, Steve Rowe) * SOLR-5291: Solrj does not propagate the root cause to the user for many errors. (Mark Miller) Optimizations ---------------------- * SOLR-5044: Admin UI - Note on Core-Admin about directories while creating core (steffkes) * SOLR-5134: Have HdfsIndexOutput extend BufferedIndexOutput. (Mark Miller, Uwe Schindler) * SOLR-5057: QueryResultCache should not related with the order of fq's list (Feihong Huang via Erick Erickson) * SOLR-4816: CloudSolrServer now uses multiple threads to send updates by default. (Joel Bernstein via Mark Miller) * SOLR-3530: Better error messages / Content-Type validation in SolrJ. (Mark Miller, hossman) Other Changes ---------------------- * SOLR-4708: Enable ClusteringComponent by default in collection1 example. The solr.clustering.enabled system property is set to 'true' by default. (ehatcher, Dawid Weiss) * SOLR-4914, SOLR-5162: Factor out core list persistence and discovery into a new CoresLocator interface. (Alan Woodward, Shawn Heisey) * SOLR-5056: Improve type safety of ConfigSolr class. (Alan Woodward) * SOLR-4951: Better randomization of MergePolicy in Solr tests (hossman) * SOLR-4953, SOLR-5108: Make XML Configuration parsing fail if an xpath matches multiple nodes when only a single value or plugin instance is expected. (hossman) * The routing parameter "shard.keys" is deprecated as part of SOLR-5017 .The new parameter name is '_route_' . The old parameter should continue to work for another release (Noble Paul) * SOLR-5173: Solr-core's Maven configuration includes test-only Hadoop dependencies as indirect compile-time dependencies. (Chris Collins, Steve Rowe) ================== 4.4.0 ================== Versions of Major Components --------------------- Apache Tika 1.4 Carrot2 3.6.2 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.5 Upgrading from Solr 4.3.0 ---------------------- * TieredMergePolicy and the various subtypes of LogMergePolicy no longer have an explicit "setUseCompoundFile" method. Instead the behavior of new segments is determined by the IndexWriter configuration, and the MergePolicy is only consulted to determine if merge segments should use the compound file format (based on the value of "setNoCFSRatio"). If you have explicitly configured one of these classes using and include an init arg like this... true ...this will now be treated as if you specified... true ...directly on the (overriding any value already set using that syntax) and a warning will be logged to updated your configuration. Users with an explicitly declared are encouraged to review the current javadocs for their MergePolicy subclass and review their configured options carefully. See SOLR-4941, SOLR-4934 and LUCENE-5038 for more information. * SOLR-4778: The signature of LogWatcher.registerListener has changed, from (ListenerConfig, CoreContainer) to (ListenerConfig). Users implementing their own LogWatcher classes will need to change their code accordingly. * LUCENE-5063: ByteField and ShortField have been deprecated and will be removed in 5.0. If you are still using these field types, you should migrate your fields to TrieIntField. Detailed Change List ---------------------- New Features ---------------------- * SOLR-3251: Dynamically add fields to schema. (Steve Rowe, Robert Muir, yonik) * SOLR-4761, SOLR-4976: Add option to plugin a merged segment warmer into solrconfig.xml. Info about segments warmed in the background is available via infostream. (Mark Miller, Ryan Ernst, Mike McCandless, Robert Muir) * SOLR-3240: Add "spellcheck.collateMaxCollectDocs" option so that when testing potential Collations against the index, SpellCheckComponent will only collect n documents, thereby estimating the hit-count. This is a performance optimization in cases where exact hit-counts are unnecessary. Also, when "collateExtendedResults" is false, this optimization is always made (James Dyer). * SOLR-4785: New MaxScoreQParserPlugin returning max() instead of sum() of terms (janhoy) * SOLR-4234: Add support for binary files in ZooKeeper. (Eric Pugh via Mark Miller) * SOLR-4048: Add findRecursive method to NamedList. (Shawn Heisey) * SOLR-4228: SolrJ's SolrPing object has new methods for ping, enable, and disable. (Shawn Heisey, hossman, Steve Rowe) * SOLR-4893: Extend FieldMutatingUpdateProcessor.ConfigurableFieldNameSelector to enable checking whether a field matches any schema field. To select field names that don't match any fields or dynamic fields in the schema, add false to an update processor's configuration in solrconfig.xml. (Steve Rowe, hossman) * SOLR-4921: Admin UI now supports adding documents to Solr (gsingers, steffkes) * SOLR-4916: Add support to write and read Solr index files and transaction log files to and from HDFS. (phunt, Mark Miller, Gregory Chanan) * SOLR-4892: Add FieldMutatingUpdateProcessorFactory subclasses Parse{Date,Integer,Long,Float,Double,Boolean}UpdateProcessorFactory. These factories have a default selector that matches all fields that either don’t match any schema field, or are in the schema with the corresponding typeClass. If they see a value that is not a CharSequence, or can't parse the value, they leave it as is. For multi-valued fields, these processors will not convert any values unless all are first successfully parsed, or already are instances of the target class. Ordering the processors, e.g. [Boolean, Long, Double, Date] will allow e.g. values ["2", "5", "8.6"] to be left alone by the Boolean and Long processors, but then converted by the Double processor. (Steve Rowe, hossman) * SOLR-4972: Add PUT command to ZkCli tool. (Roman Shaposhnik via Mark Miller) * SOLR-4973: Adding getter method for defaultCollection on CloudSolrServer. (Furkan KAMACI via Mark Miller) * SOLR-4897: Add solr/example/example-schemaless/, an example config set for schemaless mode. (Steve Rowe) * SOLR-4655: Add option to have Overseer assign generic node names so that new addresses can host shards without naming confusion. (Mark Miller, Anshum Gupta) * SOLR-4977: Add option to send IndexWriter's infostream to the logging system. (Ryan Ernst via Robert Muir) * SOLR-4693: A "deleteshard" collections API that unloads all replicas of a given shard and then removes it from the cluster state. It will remove only those shards which are INACTIVE or have no range (created for custom sharding). (Anshum Gupta, shalin) * SOLR-5003: CSV Update Handler supports optionally adding the line number/row id to a document (gsingers) * SOLR-5010: Add support for creating copy fields to the Schema REST API (gsingers) * SOLR-4991: Register QParserPlugins as SolrInfoMBeans (ehatcher) * SOLR-4943: Add a new system wide info admin handler that exposes the system info that could previously only be retrieved using a SolrCore. (Mark Miller) * SOLR-3076: Block joins. Documents and their sub-documents must be indexed as a block. {!parent which=} takes in a query that matches child documents and results in matches on their parents. {!child of=} takes in a query that matches some parent documents and results in matches on their children. (Mikhail Khludnev, Vadim Kirilchuk, Alan Woodward, Tom Burton-West, Mike McCandless, hossman, yonik) Bug Fixes ---------------------- * SOLR-4333: edismax parser to not double-escape colons if already escaped by the client application (James Dyer, Robert J. van der Boon) * SOLR-4776: Solrj doesn't return "between" count in range facets (Philip K. Warren via shalin) * SOLR-4616: HitRatio on caches is now exposed over JMX MBeans as a float. (Greg Bowyer) * SOLR-4803: Fixed core discovery mode (ie: new style solr.xml) to treat 'collection1' as the default core name. (hossman) * SOLR-4790: Throw an error if a core has the same name as another core, both old and new style solr.xml * SOLR-4842: Fix facet.field local params from affecting other facet.field's. (ehatcher, hossman) * SOLR-4814: If a SolrCore cannot be created it should remove any information it published about itself from ZooKeeper. (Mark Miller) * SOLR-4863: Removed non-existent attribute sourceId from dynamic JMX stats to fix AttributeNotFoundException (suganuma, hossman via shalin) * SOLR-4891: JsonLoader should preserve field value types from the JSON content stream. (Steve Rowe) * SOLR-4805: SolrCore#reload should not call preRegister and publish a DOWN state to ZooKeeper. (Mark Miller, Jared Rodriguez) * SOLR-4899: When reconnecting after ZooKeeper expiration, we need to be willing to wait forever, not just for 30 seconds. (Mark Miller) * SOLR-4920: JdbcDataSource incorrectly suppresses exceptions when retrieving a connection from a JNDI context and falls back to trying to use DriverManager to obtain a connection. Additionally, if a SQLException is thrown while initializing a connection, such as in setAutoCommit(), the connection will not be closed. (Chris Eldredge via shalin) * SOLR-4915: The root cause should be returned to the user when a SolrCore create call fails. (Mark Miller) * SOLR-4925 : Collection create throws NPE when 'numShards' param is missing (Noble Paul) * SOLR-4910: persisting solr.xml is broken. More stringent testing of persistence fixed up a number of issues and several bugs with persistence. Among them are - don't persisting implicit properties - should persist zkHost in the tag (user's list) - reloading a core that has transient="true" returned an error. reload should load a transient core if it's not yet loaded. - No longer persisting loadOnStartup or transient core properties if they were not specified in the original solr.xml - Testing flushed out the fact that you couldn't swap a core marked transient=true loadOnStartup=false because it hadn't been loaded yet. - SOLR-4862, CREATE fails to persist schema, config, and dataDir - SOLR-4363, not persisting coreLoadThreads in tag - SOLR-3900, logWatcher properties not persisted - SOLR-4850, cores defined as loadOnStartup=true, transient=false can't be searched (Erick Erickson) * SOLR-4923: Commits to non leaders as part of a request that also contain updates can execute out of order. (hossman, Ricardo Merizalde, Mark Miller) * SOLR-4932: persisting solr.xml saves some parameters it shouldn't when they weren't defined in the original. Benign since the default values are saved, but still incorrect. (Erick Erickson, thanks Shawn Heisey for helping test!) * SOLR-4934, SOLR-4941: Fix handling of init arg "useCompoundFile" needed after changes in LUCENE-5038 (hossman) * SOLR-4456: Admin UI: Displays dashboard even if Solr is down (steffkes) * SOLR-4949: UI Analysis page dropping characters from input box (steffkes) * SOLR-4960: Fix race conditions in shutdown of CoreContainer and getCore that could cause a request to attempt to use a core that has shut down. (yonik) * SOLR-4926: Fixed rare replication bug that normally only manifested when using compound file format. (yonik, Mark Miller) * SOLR-4974: Outgrowth of SOLR-4960 that includes transient cores and pending cores (Erick Erickson) * SOLR-3369: shards.tolerant=true is broken for group queries (Russell Black, Martijn van Groningen, Jabouille jean Charles, Ryan McKinley via shalin) * SOLR-4452: Hunspell stemmer should not merge duplicate dictionary entries (janhoy) * SOLR-5000: ManagedIndexSchema doesn't persist uniqueKey tag after calling addFields method. (Jun Ohtani, Steve Rowe) * SOLR-4982: Creating a core while referencing system properties looks like it loses files Actually, instanceDir, config, dataDir and schema are not dereferenced properly when creating cores that reference sys vars (e.g. &dataDir=${dir}). In the dataDir case in particular this leads to the index being put in a directory literally named ${dir} but on restart the sysvar will be properly dereferenced. * SOLR-4788: Multiple Entities DIH delta import: dataimporter.[entityName].last_index_time is empty. (chakming wong, James Dyer via shalin) * SOLR-4978: Time is stripped from datetime column when imported into Solr date field if convertType=true. (Bill Au, shalin) * SOLR-5019: spurious ConcurrentModificationException when spell check component was in use with filters. (yonik) * SOLR-5018: The Overseer should avoid publishing the state for collections that do not exist under the /collections zk node. (Mark Miller) * SOLR-5028,SOLR-5029: ShardHandlerFactory was not being created properly when using new-style solr.xml, and was not being persisted properly when using old-style. (Tomás Fernández Löbbe, Ryan Ernst, Alan Woodward) * SOLR-4997: The splitshard api doesn't call commit on new sub shards before switching shard states. Multiple bugs related to sub shard recovery and replication are also fixed. (shalin) * SOLR-5034: A facet.query that parses or analyzes down to a null Query would throw a NPE. Fixed. (David Smiley) * SOLR-5039: Admin/Schema Browser displays -1 for term counts for multiValued fields. * SOLR-5037: The CSV loader now accepts field names that are not in the schema. (gsingers, ehatcher, Steve Rowe) * SOLR-4791: solr.xml sharedLib does not work in 4.3.0 (Ryan Ernst, Jan Høydahl via Erick Erickson) Optimizations ---------------------- * SOLR-4923: Commit to all nodes in a collection in parallel rather than locally and then to all other nodes. (hossman, Ricardo Merizalde, Mark Miller) * SOLR-3838: Admin UI - Multiple filter queries are not supported in Query UI (steffkes) * SOLR-4719 : Admin UI - Default to wt=json on Query-Screen (steffkes) * SOLR-4611: Admin UI - Analysis-Urls with empty parameters create empty result table (steffkes) * SOLR-4955: Admin UI - Show address bar on top for Schema + Config (steffkes) * SOLR-4412: New parameter langid.lcmap to map detected language code to be placed in "language" field (janhoy) * SOLR-4815: Admin-UI - DIH: Let "commit" be checked by default (steffkes) * SOLR-5002: optimize numDocs(Query,DocSet) when filterCache is null (Robert Muir) * SOLR-5012: optimize search with filter when filterCache is null (Robert Muir) Other Changes ---------------------- * SOLR-4737: Update Guava to 14.0.1 (Mark Miller) * SOLR-2079: Add option to pass HttpServletRequest in the SolrQueryRequest context map. (Tomás Fernández Löbbe via Robert Muir) * SOLR-4738: Update Jetty to 8.1.10.v20130312 (Mark Miller, Robert Muir) * SOLR-4749: Clean up and refactor CoreContainer code around solr.xml and SolrCore management. (Mark Miller) * SOLR-4547: Move logging of filenames on commit from INFO to DEBUG. (Shawn Heisey, hossman) * SOLR-4757: Change the example to use the new solr.xml format and core discovery by directory structure. (Mark Miller) * SOLR-4759: Velocity (/browse) template cosmetic cleanup. (Mark Bennett, ehatcher) * SOLR-4778: LogWatcher init code moved out of CoreContainer (Alan Woodward) * SOLR-4784: Make class LuceneQParser public (janhoy) * SOLR-4448: Allow the solr internal load balancer to be more easily pluggable. (Philip Hoy via Robert Muir) * SOLR-4224: Refactor JavaBinCodec input stream definition to enhance reuse. (phunt via Mark Miller) * SOLR-4931: SolrDeletionPolicy onInit and onCommit methods changed to override exact signatures (with generics) from IndexDeletionPolicy (shalin) * SOLR-4942: test improvements to randomize use of compound files (hossman) * SOLR-4966: CSS, JS and other files in webapp without license (uschindler, steffkes) * SOLR-4986: Upgrade to Tika 1.4 (Markus Jelsma via janhoy) * SOLR-4948, SOLR-5009: Tidied up CoreContainer construction logic. (Alan Woodward, Uwe Schindler, Steve Rowe) * LUCENE-5107: Properties files by Solr are now written in UTF-8 encoding, Unicode is no longer escaped. Reading of legacy properties files with \u escapes is still possible. (Uwe Schindler, Robert Muir) ================== 4.3.1 ================== Versions of Major Components --------------------- Apache Tika 1.3 Carrot2 3.6.2 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.5 Detailed Change List ---------------------- Bug Fixes ---------------------- * SOLR-4795: Sub shard leader should not accept any updates from parent after it goes active (shalin) * SOLR-4798: shard splitting does not respect the router for the collection when executing the index split. One effect of this is that documents may be placed in the wrong shard when the default compositeId router is used in conjunction with IDs containing "!". (yonik) * SOLR-4797: Shard splitting creates sub shards which have the wrong hash range in cluster state. This happens when numShards is not a power of two and router is compositeId. (shalin) * SOLR-4806: Shard splitting does not abort if WaitForState times out (shalin) * SOLR-4807: The zkcli script now works with log4j. The zkcli.bat script was broken on Windows in 4.3.0, now it works. (Shawn Heisey) * SOLR-4813: Fix SynonymFilterFactory to allow init parameters for tokenizer factory used when parsing synonyms file.

The URL format remains the same: all resource names are lowercase. See SOLR-4623 for details. * Slf4j/logging jars are no longer included in the Solr webapp. All logging jars are now in example/lib/ext. Changing logging impls is now as easy as updating the jars in this folder with those necessary for the logging impl you would like. If you are using another webapp container, these jars will need to go in the corresponding location for that container. In conjunction, the dist-excl-slf4j and dist-war-excl-slf4 build targets have been removed since they are redundant. See the Slf4j documentation, SOLR-3706, and SOLR-4651 for more details. * The hardcoded SolrCloud defaults for 'hostContext="solr"' and 'hostPort="8983"' have been deprecated and will be removed in Solr 5.0. Existing solr.xml files that do not have these options explicitly specified should be updated accordingly. See SOLR-4622 for more details. Detailed Change List ---------------------- New Features ---------------------- * SOLR-4648 PreAnalyzedUpdateProcessorFactory allows using the functionality of PreAnalyzedField with other field types. See javadoc for details and examples. (Andrzej Bialecki) * SOLR-4623: Provide REST API read access to all elements of the live schema. Add a REST API request to return the entire live schema, in JSON, XML, and schema.xml formats. Move REST API methods from package org.apache.solr.rest to org.apache.solr.rest.schema, and rename base functionality REST API classes to remove the current schema focus, to prepare for other non-schema REST APIs. Change output path for copyFields and dynamicFields from "copyfields" and "dynamicfields" (all lowercase) to "copyFields" and "dynamicFields", respectively, to align with all other REST API outputs, which use camelCase. (Steve Rowe) * SOLR-4658: In preparation for REST API requests that can modify the schema, a "managed schema" is introduced. Add '' to solrconfig.xml in order to use it, and to enable schema modifications via REST API requests. (Steve Rowe, Robert Muir) * SOLR-4656: Added two new highlight parameters, hl.maxMultiValuedToMatch and hl.maxMultiValuedToExamine. maxMultiValuedToMatch stops looking for snippets after finding the specified number of matches, no matter how far into the multivalued field you've gone. maxMultiValuedToExamine stops looking for matches after the specified number of multiValued entries have been examined. If both are specified, the limit hit first stops the loop. Also this patch cuts down on the copying of the document entries during highlighting. These optimizations are probably unnoticeable unless there are a large number of entries in the multiValued field. Conspicuously, this will prevent the "best" match from being found if it appears later in the MV list than the cutoff specified by either of these params. (Erick Erickson) * SOLR-4675: Improve PostingsSolrHighlighter to support per-field/query-time overrides and add additional configuration parameters. See the javadocs for more details and examples. (Robert Muir) * SOLR-3755: A new collections api to add additional shards dynamically by splitting existing shards. (yonik, Anshum Gupta, shalin) * SOLR-4530: DIH: Provide configuration to use Tika's IdentityHtmlMapper (Alexandre Rafalovitch via shalin) * SOLR-4662: Discover SolrCores by directory structure rather than defining them in solr.xml. Also, change the format of solr.xml to be closer to that of solrconfig.xml. This version of Solr will ship the example in the old style, but you can manually try the new style. Solr 4.4 will ship with the new style, and Solr 5.0 will remove support for the old style. (Erick Erickson, Mark Miller) Additional Work: - SOLR-4347: Ensure that newly-created cores via Admin handler are persisted in solr.xml (Erick Erickson) - SOLR-1905: Cores created by the admin request handler should be persisted to solr.xml. Also fixed a problem whereby properties like solr.solr.datadir would be persisted to solr.xml. Also, cores that didn't happen to be loaded were not persisted. (Erick Erickson) * SOLR-4717/SOLR-1351: SimpleFacets now work with localParams allowing faceting on the same field multiple ways (ryan, Uri Boness) * SOLR-4671: CSVResponseWriter now supports pseudo fields. (ryan, nihed mbarek) * SOLR-4358: HttpSolrServer sends the stream name and exposes 'useMultiPartPost' (Karl Wright via ryan) Bug Fixes ---------------------- * SOLR-4543: setting shardHandlerFactory in solr.xml/solr.properties does not work.

(Mark Miller) * SOLR-4405: Admin UI - admin-extra files are not rendered into the core-menu (steffkes) * SOLR-3956: Fixed group.facet=true to work with negative facet.limit (Chris van der Merwe, hossman) * SOLR-4650: copyField doesn't work with source globs that don't match any explicit or dynamic fields. This regression was introduced in Solr 4.2. (Daniel Collins, Steve Rowe) * SOLR-4641: Schema now throws exception on illegal field parameters. (Robert Muir) * SOLR-3758: Fixed SpellCheckComponent to work consistently with distributed grouping (James Dyer) * SOLR-4652: Fix broken behavior with shared libraries in resource loader for solr.xml plugins. (Ryan Ernst, Robert Muir, Uwe Schindler) * SOLR-4664: ZkStateReader should update aliases on construction. (Mark Miller, Elodie Sannier) * SOLR-4682: CoreAdminRequest.mergeIndexes can not merge multiple cores or indexDirs. (Jason.D.Cao via shalin) * SOLR-4581: When faceting on numeric fields in Solr 4.2, negative values (constraints) were sorted incorrectly. (Alexander Buhr, shalin, yonik) * SOLR-4699: The System admin handler should not assume a file system based data directory location. (Mark Miller) * SOLR-4695: Fix core admin SPLIT action to be useful with non-cloud setups (shalin) * SOLR-4680: Correct example spellcheck configuration's queryAnalyzerFieldType and use "text" field instead of narrower "name" field (ehatcher, Mark Bennett) * SOLR-4702: Fix example /browse "Did you mean?" suggestion feature. (ehatcher, Mark Bennett) * SOLR-4710: You cannot delete a collection fully from ZooKeeper unless all nodes are up and functioning correctly. (Mark Miller) * SOLR-4487: SolrExceptions thrown by HttpSolrServer will now contain the proper HTTP status code returned by the remote server, even if that status code is not something Solr itself returned -- eg: from the Servlet Container, or an intermediate HTTP Proxy (hossman) * SOLR-4661: Admin UI Replication details now correctly displays the current replicable generation/version of the master. (hossman) * SOLR-4716,SOLR-4584: SolrCloud request proxying does not work on Tomcat and perhaps other non Jetty containers. (Po Rui, Yago Riveiro via Mark Miller) * SOLR-4746: Distributed grouping used a NamedList instead of a SimpleOrderedMap for the top level group commands, causing output formatting differences compared to non-distributed grouping. (yonik) * SOLR-4705: Fixed bug causing NPE when querying a single replica in SolrCloud using the shards param (Raintung Li, hossman) * SOLR-4729: LukeRequestHandler: Using a dynamic copyField source that is not also a dynamic field triggers error message 'undefined field: "(glob)"'. (Adam Hahn, hossman, Steve Rowe) Optimizations ---------------------- Other Changes ---------------------- * SOLR-4653: Solr configuration should log inaccessible/ non-existent relative paths in lib dir=...

(Yonik Seeley, Robert Muir) * SOLR-3706: Ship setup to log with log4j. (ryan, Mark Miller) * SOLR-4651: Remove dist-excl-slf4j build target. (Shawn Heisey) * SOLR-4622: The hardcoded SolrCloud defaults for 'hostContext="solr"' and 'hostPort="8983"' have been deprecated and will be removed in Solr 5.0. Existing solr.xml files that do not have these options explicitly specified should be updated accordingly. (hossman) * SOLR-4672: Requests attempting to use SolrCores which had init failures (that would be reported by CoreAdmin STATUS requests) now result in 500 error responses with the details about the init failure, instead of 404 error responses. (hossman) * SOLR-4730: Make the wiki link more prominent in the release documentation. (Uri Laserson via Robert Muir) ================== 4.2.1 ================== Versions of Major Components --------------------- Apache Tika 1.3 Carrot2 3.6.2 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.5 Detailed Change List ---------------------- Bug Fixes ---------------------- * SOLR-4567: copyField source glob matching explicit field(s) stopped working in Solr 4.2. (Alexandre Rafalovitch, Steve Rowe) * SOLR-4475: Fix various places that still assume File based paths even when not using a file based DirectoryFactory. (Mark Miller) * SOLR-4551: CachingDirectoryFactory needs to create CacheEntry's with the fullpath not path. (Mark Miller) * SOLR-4555: When forceNew is used with CachingDirectoryFactory#get, the old CacheValue should give up its path as it will be used by a new Directory instance. (Mark Miller) * SOLR-4578: CoreAdminHandler#handleCreateAction gets a SolrCore and does not close it in SolrCloud mode when a core with the same name already exists. (Mark Miller) * SOLR-4574: The Collections API will silently return success on an unknown ACTION parameter. (Mark Miller) * SOLR-4576: Collections API validation errors should cause an exception on clients and otherwise act as validation errors with the Core Admin API. (Mark Miller) * SOLR-4577: The collections API should return responses (success or failure) for each node it attempts to work with. (Mark Miller) * SOLR-4568: The lastPublished state check before becoming a leader is not working correctly. (Mark Miller) * SOLR-4570: Even if an explicit shard id is used, ZkController#preRegister should still wait to see the shard id in its current ClusterState. (Mark Miller) * SOLR-4585: The Collections API validates numShards with < 0 but should use <= 0. (Mark Miller) * SOLR-4592: DefaultSolrCoreState#doRecovery needs to check the CoreContainer shutdown flag inside the recoveryLock sync block. (Mark Miller) * SOLR-4595: CachingDirectoryFactory#close can throw a concurrent modification exception. (Mark Miller) * SOLR-4573: Accessing Admin UI files in SolrCloud mode logs warnings. (Mark Miller, Phil John) * SOLR-4594: StandardDirectoryFactory#remove accesses byDirectoryCache without a lock. (Mark Miller) * SOLR-4597: CachingDirectoryFactory#remove should not attempt to empty/remove the index right away but flag for removal after close. (Mark Miller) * SOLR-4598: The Core Admin unload command's option 'deleteDataDir', should use the DirectoryFactory API to remove the data dir. (Mark Miller) * SOLR-4599: CachingDirectoryFactory calls close(Directory) on forceNew if the Directory has a refCnt of 0, but it should call closeDirectory(CacheValue). (Mark Miller) * SOLR-4602: ZkController#unregister should cancel its election participation before asking the Overseer to delete the SolrCore information. (Mark Miller) * SOLR-4601: A Collection that is only partially created and then deleted will leave pre allocated shard information in ZooKeeper. (Mark Miller) * SOLR-4604: UpdateLog#init is over called on SolrCore#reload. (Mark Miller) * SOLR-4605: Rollback does not work correctly. (Mark S, Mark Miller) * SOLR-4609: The Collections API should only send the reload command to ACTIVE cores. (Mark Miller) * SOLR-4297: Atomic update request containing null=true sets all subsequent fields to null (Ben Pennell, Rob, shalin) * SOLR-4371: Admin UI - Analysis Screen shows empty result (steffkes) * SOLR-4318: NPE encountered with querying with wildcards on a field that uses the DefaultAnalyzer (i.e. no analysis chain defined). (Erick Erickson) * SOLR-4361: DataImportHandler would throw UnsupportedOperationException if handler-level parameters were specified containing periods in the name (James Dyer) * SOLR-4538: Date Math expressions were being truncated to 32 characters when used in field:value queries in the lucene QParser. (hossman, yonik) * SOLR-4617: SolrCore#reload needs to pass the deletion policy to the next SolrCore through its constructor rather than setting a field after. (Mark Miller) * SOLR-4589: Fixed CPU spikes and poor performance in lazy field loading of multivalued fields. (hossman) * SOLR-4608: Update Log replay and PeerSync replay should use the default processor chain to update the index. (Ludovic Boutros, yonik) * SOLR-4625: The solr (lucene syntax) query parser lost top-level boost values and top-level phrase slops on queries produced by nested sub-parsers. (yonik) * SOLR-4624: CachingDirectoryFactory does not need to support forceNew any longer and it appears to be causing a missing close directory bug. forceNew is no longer respected and will be removed in 4.3. (Mark Miller) * SOLR-3819: Grouped faceting (group.facet=true) did not respect filter exclusions. (Petter Remen, yonik) * SOLR-4637: Replication can sometimes wait until shutdown or core unload until removing some tmp directories. (Mark Miller) * SOLR-4638: DefaultSolrCoreState#getIndexWriter(null) is a way to avoid creating the IndexWriter earlier than necessary, but it's not implemented quite right. (Mark Miller) * SOLR-4640: CachingDirectoryFactory can fail to close directories in some race conditions. (Mark Miller) * SOLR-4642: QueryResultKey is not calculating the correct hashCode for filters. (Joel Bernstein via Mark Miller) Optimizations ---------------------- * SOLR-4569: waitForReplicasToComeUp should bail right away if it doesn't see the expected slice in the clusterstate rather than waiting. (Mark Miller) * SOLR-4311: Admin UI - Optimize Caching Behaviour (steffkes) Other Changes ---------------------- * SOLR-4537: Clean up schema information REST API. (Steve Rowe) * SOLR-4596: DistributedQueue should ensure its full path exists in the constructor.

(Mark Miller) * SOLR-4210: Requests to a Collection that does not exist on the receiving node should be proxied to a suitable node. (Mark Miller, Po Rui, yonik) * SOLR-1365: New SweetSpotSimilarityFactory allows customizable TF/IDF based Similarity when you know the optimal "Sweet Spot" of values for the field length and TF scoring factors. (hossman) * SOLR-4138: CurrencyField fields can now be used in a ValueSources to get the "raw" value (using the default number of fractional digits) in the default currency of the field type. There is also a new currency(field,[CODE]) function for generating a ValueSource of the "natural" value, converted to an optionally specified currency to override the default for the field type. (hossman) * SOLR-4503: Add REST API methods, via Restlet integration, for reading schema elements, at /schema/fields/, /schema/dynamicfields/, /schema/fieldtypes/, and /schema/copyfields/.

(Mark Miller) * SOLR-4459: The Replication 'index move' rather than copy optimization doesn't kick in when using NRTCachingDirectory or the rate limiting feature. (Mark Miller) * SOLR-4421,SOLR-4165: On CoreContainer shutdown, all SolrCores should publish their state as DOWN. (Mark Miller, Markus Jelsma) * SOLR-4467: Ephemeral directory implementations may not recover correctly because the code to clear the tlog files on startup is off. (Mark Miller) * SOLR-4413: Fix SolrCore#getIndexDir() to return the current index directory. (Gregg Donovan, Mark Miller) * SOLR-4469: A new IndexWriter must be opened on SolrCore reload when the index directory has changed and the previous SolrCore's state should not be propagated. (Mark Miller, Gregg Donovan) * SOLR-4471: Replication occurs even when a slave is already up to date. (Mark Miller, Andre Charton) * SOLR-4484: ReplicationHandler#loadReplicationProperties still uses Files rather than the Directory to try and read the replication properties files. (Mark Miller) * SOLR-4352: /browse pagination now supports and preserves sort context (Eric Spiegelberg, Erik Hatcher) * LUCENE-4796, SOLR-4373: Fix concurrency issue in NamedSPILoader and AnalysisSPILoader when doing concurrent core loads in multicore Solr configs. (Uwe Schindler, Hossman) * SOLR-4504: Fixed CurrencyField range queries to correctly exclude documents w/o values (hossman) * SOLR-4480: A trailing + or - caused the edismax parser to throw an exception. (Fiona Tay, Jan Høydahl, yonik) * SOLR-4507: The Cloud tab does not show up in the Admin UI if you set zkHost in solr.xml. (Alfonso Presa, Mark Miller) * SOLR-4505: Possible deadlock around SolrCoreState update lock. (Erick Erickson, Mark Miller) * SOLR-4511: When a new index is replicated into place, we need to update the most recent replicatable index point without doing a commit. This is important for repeater use cases, as well as when nodes may switch master/slave roles. (Mark Miller, Raúl Grande) * SOLR-4515: CurrencyField's OpenExchangeRatesOrgProvider now requires a ratesFileLocation init param, since the previous global default no longer works (hossman) * SOLR-4518: Improved CurrencyField error messages when attempting to use a Currency that is not supported by the current JVM. (hossman) * SOLR-3798: Fix copyField implementation in IndexSchema to handle dynamic field references that aren't string-equal to the name of the referenced dynamic field.

This will keep some less common unnecessary replications from happening. (Mark Miller, Simon Scofield) * SOLR-4529: Improve Admin UI Dashboard legibility (Felix Buenemann via steffkes) * SOLR-4526: Admin UI depends on optional system info (Felix Buenemann via steffkes) Other Changes ---------------------- * SOLR-4259: Carrot2 dependency should be declared on the mini version, not the core.

(Markus Jelsma via Mark Miller) * SOLR-4200: Reduce INFO level logging from CachingDirectoryFactory (Shawn Heisey via hossman) ================== 4.1.0 ================== Versions of Major Components --------------------- Apache Tika 1.2 Carrot2 3.6.2 Velocity 1.7 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.4.5 Upgrading from Solr 4.0.0 ---------------------- Custom java parsing plugins need to migrate from throwing the internal ParseException to throwing SyntaxError. BaseDistributedSearchTestCase now randomizes the servlet context it uses when creating Jetty instances. Subclasses that assume a hard coded context of "/solr" should either be fixed to use the "String context" variable, or should take advantage of the new BaseDistributedSearchTestCase(String) constructor to explicitly specify a fixed servlet context path. See SOLR-4136 for details. Detailed Change List ---------------------- New Features ---------------------- * SOLR-2255: Enhanced pivot faceting to use local-params in the same way that regular field value faceting can. This means support for excluding a filter query, using a different output key, and specifying 'threads' to do facet.method=fcs concurrently. PivotFacetHelper now extends SimpleFacet and the getFacetImplementation() extension hook was removed. (dsmiley) * SOLR-3897: A highlighter parameter "hl.preserveMulti" to return all of the values of a multiValued field in their original order when highlighting. (Joel Bernstein via yonik) * SOLR-3929: Support configuring IndexWriter max thread count in solrconfig. (phunt via Mark Miller) * SOLR-3906: Add support for AnalyzingSuggester (LUCENE-3842), where the underlying analyzed form used for suggestions is separate from the returned text. (Robert Muir) * SOLR-3985: ExternalFileField caches can be reloaded on firstSearcher/ newSearcher events using the ExternalFileFieldReloader (Alan Woodward) * SOLR-3911: Make Directory and DirectoryFactory first class so that the majority of Solr's features work with any custom implementations. (Mark Miller) Additional Work: - SOLR-4032: Files larger than an internal buffer size fail to replicate. (Mark Miller, Markus Jelsma) - SOLR-4033: Consistently use the solrconfig.xml lockType everywhere. (Mark Miller, Markus Jelsma) - SOLR-4144: Replication using too much RAM. (yonik, Markus Jelsma) - SOLR-4187: NPE on Directory release (Mark Miller, Markus Jelsma) * SOLR-4051: Add element to DIH's data-config.xml file, allowing the user to specify the location, filename and Locale for the "data-config.properties" file. Alternatively, users can specify their own property writer implementation for greater control. This new configuration element is optional, and defaults mimic prior behavior. The one exception is that the "root" locale is default. Previously it was the machine's default locale. (James Dyer) * SOLR-4084: Add FuzzyLookupFactory, which is like AnalyzingSuggester except that it can tolerate typos in the input. (Areek Zillur via Robert Muir) * SOLR-4088: New and improved auto host detection strategy for SolrCloud. (Raintung Li via Mark Miller) * SOLR-3970: SystemInfoHandler now exposes more details about the JRE/VM/Java version in use. (hossman) * SOLR-4101: Add support for storing term offsets in the index via a 'storeOffsetsWithPositions' flag on field definitions in the schema. (Tom Winch, Alan Woodward) * SOLR-4093: Solr QParsers may now be directly invoked in the lucene query syntax without the _query_ magic field hack. Example: foo AND {!term f=myfield v=$qq} (yonik) * SOLR-4087: Add MAX_DOC_FREQ option to MoreLikeThis. (Andrew Janowczyk via Mark Miller) * SOLR-4114: Allow creating more than one shard per instance with the Collection API. (Per Steffensen, Mark Miller) * SOLR-3531: Allowing configuring maxMergeSizeMB and maxCachedMB when using NRTCachingDirectoryFactory. (Andy Laird via Mark Miller) * SOLR-4118: Fix replicationFactor to align with industry usage. replicationFactor now means the total number of copies of a document stored in the collection (or the total number of physical indexes for a single logical slice of the collection). For example if replicationFactor=3 then for a given shard there will be a total of 3 replicas (one of which will normally be designated as the leader.) (yonik) * SOLR-4124: You should be able to set the update log directory with the CoreAdmin API the same way as the data directory. (Mark Miller) * SOLR-4028: When using ZK chroot, it would be nice if Solr would create the initial path when it doesn't exist. (Tomás Fernández Löbbe via Mark Miller) * SOLR-3948: Calculate/display deleted documents in admin interface. (Shawn Heisey via Mark Miller) * SOLR-4030: Allow rate limiting Directory IO based on the IO context.

(Per Steffensen via Mark Miller) * SOLR-4110: Configurable Content-Type headers for PHPResponseWriters and PHPSerializedResponseWriter. (Dominik Siebel via Mark Miller) * SOLR-1028: The ability to specify "transient" and "loadOnStartup" as a new properties of tags in solr.xml. Can specify "transientCacheSize" in the tag. Together these allow cores to be loaded only when needed and only transientCacheSize transient cores will be loaded at a time, the rest aged out on an LRU basis. * SOLR-4246: When update.distrib is set to skip update processors before the distributed update processor, always include the log update processor so forwarded updates will still be logged. (yonik) * SOLR-4230: The new Solr 4 spatial fields now work with the {!geofilt} and {!bbox} query parsers. The score local-param works too. (David Smiley) * SOLR-1972: Add extra statistics to RequestHandlers - 5 & 15-minute reqs/sec rolling averages; median, 75th, 95th, 99th, 99.9th percentile request times (Alan Woodward, Shawn Heisey, Adrien Grand, Uwe Schindler) * SOLR-4271: Add support for PostingsHighlighter. (Robert Muir) * SOLR-4255: The new Solr 4 spatial fields now have a 'filter' boolean local-param that can be set to false to not filter. It's useful when there is already a spatial filter query but you also need to sort or boost by distance. (David Smiley) * SOLR-4265, SOLR-4283: Solr now parses request parameters (in URL or sent with POST using content-type application/x-www-form-urlencoded) in its dispatcher code. It no longer relies on special configuration settings in Tomcat or other web containers to enable UTF-8 encoding, which is mandatory for correct Solr behaviour. Query strings passed in via the URL need to be properly-%-escaped, UTF-8 encoded bytes, otherwise Solr refuses to handle the request. The maximum length of x-www-form-urlencoded POST parameters can now be configured through the requestDispatcher/requestParsers/@formdataUploadLimitInKB setting in solrconfig.xml (defaults to 2 MiB). Solr now works out of the box with e.g. Tomcat, JBoss,... (Uwe Schindler, Dawid Weiss, Alex Rocher) * SOLR-2201: DIH's "formatDate" function now supports a timezone as an optional fourth parameter (James Dyer, Mark Waddle) * SOLR-4302: New parameter 'indexInfo' (defaults to true) in CoreAdmin STATUS command can be used to omit index specific information (Shahar Davidson via shalin) * SOLR-2592: Collection specific document routing. The "compositeId" router is the default for collections with hash based routing (i.e. when numShards=N is specified on collection creation). Documents with ids sharing the same domain (prefix) will be routed to the same shard, allowing for efficient querying. Example: The following two documents will be indexed to the same shard since they share the same domain "customerB!". {"id" : "customerB!doc1" [...] } {"id" : "customerB!doc2" [...] } At query time, one can specify a "shard.keys" parameter that lists what shards the query should cover. http://.../query?q=my_query&shard.keys=customerB! Collections that do not specify numShards at collection creation time use custom sharding and default to the "implicit" router. Document updates received by a shard will be indexed to that shard, unless a "_shard_" parameter or document field names a different shard.

(Raintung Li, Per Steffensen via Mark Miller) * SOLR-3993: If multiple SolrCore's for a shard coexist on a node, on cluster restart, leader election would stall until timeout, waiting to see all of the replicas come up. (Mark Miller, Alexey Kudinov) * SOLR-2045: Databases that require a commit to be issued before closing the connection on a non-read-only database leak connections. Also expanded the SqlEntityProcessor test to sometimes use Derby as well as HSQLDB (Derby is one db affected by this bug). (Fenlor Sebastia, James Dyer) * SOLR-4064: When there is an unexpected exception while trying to run the new leader process, the SolrCore will not correctly rejoin the election.

(Mark Miller) ================== 4.0.0 ================== Versions of Major Components --------------------- Apache Tika 1.2 Carrot2 3.5.0 Velocity 1.6.4 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.3.6 Upgrading from Solr 4.0.0-BETA ---------------------- In order to better support distributed search mode, the TermVectorComponent's response format has been changed so that if the schema defines a uniqueKeyField, then that field value is used as the "key" for each document in its response section, instead of the internal lucene doc id. Users w/o a uniqueKeyField will continue to see the same response format. See SOLR-3229 for more details. If you are using SolrCloud's distributed update request capabilities and a non string type id field, you must re-index. Upgrading from Solr 4.0.0-ALPHA ---------------------- Solr is now much more strict about requiring that the uniqueKeyField feature (if used) must refer to a field which is not multiValued. If you upgrade from an earlier version of Solr and see an error that your uniqueKeyField "can not be configured to be multivalued" please add 'multiValued="false"' to the declaration for your uniqueKeyField. See SOLR-3682 for more details. In addition, please review the notes above about upgrading from 4.0.0-BETA Upgrading from Solr 3.6 ---------------------- * The Lucene index format has changed and as a result, once you upgrade, previous versions of Solr will no longer be able to read your indices. In a master/slave configuration, all searchers/slaves should be upgraded before the master. If the master were to be updated first, the older searchers would not be able to read the new index format. * Setting abortOnConfigurationError=false is no longer supported (since it has never worked properly). Solr will now warn you if you attempt to set this configuration option at all. (see SOLR-1846) * The default logic for the 'mm' param of the 'dismax' QParser has been changed. If no 'mm' param is specified (either in the query, or as a default in solrconfig.xml) then the effective value of the 'q.op' param (either in the query or as a default in solrconfig.xml or from the 'defaultOperator' option in schema.xml) is used to influence the behavior. If q.op is effectively "AND" then mm=100%. If q.op is effectively "OR" then mm=0%. Users who wish to force the legacy behavior should set a default value for the 'mm' param in their solrconfig.xml file. * The VelocityResponseWriter is no longer built into the core. Its JAR and dependencies now need to be added (via or solr/home lib inclusion), and it needs to be registered in solrconfig.xml like this: * The update request parameter to choose Update Request Processor Chain is renamed from "update.processor" to "update.chain". The old parameter was deprecated but still working since Solr3.2, but is now removed entirely. * The and sections of solrconfig.xml are discontinued and replaced with the section. There are also better defaults. When migrating, if you don't know what your old settings mean, simply delete both and sections. If you have customizations, put them in section - with same syntax as before. * Two of the SolrServer subclasses in SolrJ were renamed/replaced. CommonsHttpSolrServer is now HttpSolrServer, and StreamingUpdateSolrServer is now ConcurrentUpdateSolrServer. * The PingRequestHandler no longer looks for a option in the (legacy) section of solrconfig.xml. Users who wish to take advantage of this feature should configure a "healthcheckFile" init param directly on the PingRequestHandler. As part of this change, relative file paths have been fixed to be resolved against the data dir. See the example solrconfig.xml and SOLR-1258 for more details. * Due to low level changes to support SolrCloud, the uniqueKey field can no longer be populated via or in the schema.xml. Users wishing to have Solr automatically generate a uniqueKey value when adding documents should instead use an instance of solr.UUIDUpdateProcessorFactory in their update processor chain. See SOLR-2796 for more details. In addition, please review the notes above about upgrading from 4.0.0-BETA, and 4.0.0-ALPHA Detailed Change List ---------------------- New Features ---------------------- * SOLR-3670: New CountFieldValuesUpdateProcessorFactory makes it easy to index the number of values in another field for later use at query time. (hossman) * SOLR-2768: new "mod(x,y)" function for computing the modulus of two value sources. (hossman) * SOLR-3238: Numerous small improvements to the Admin UI (steffkes) * SOLR-3597: seems like a lot of wasted whitespace at the top of the admin screens (steffkes) * SOLR-3304: Added Solr adapters for Lucene 4's new spatial module. With SpatialRecursivePrefixTreeFieldType ("location_rpt" in example schema), it is possible to index a variable number of points per document (and sort on them), index not just points but any Spatial4j supported shape such as polygons, and to query on these shapes too. Polygons requires adding JTS to the classpath. (David Smiley) * SOLR-3825: Added optional capability to log what ids are in a response (Scott Stults via gsingers) * SOLR-3821: Added 'df' to the UI Query form (steffkes) * SOLR-3822: Added hover titles to the edismax params on the UI Query form (steffkes) Optimizations ---------------------- * SOLR-3715: improve concurrency of the transaction log by removing synchronization around log record serialization. (yonik) * SOLR-3807: Currently during recovery we pause for a number of seconds after waiting for the leader to see a recovering state so that any previous updates will have finished before our commit on the leader - we don't need this wait for peersync. (Mark Miller) * SOLR-3837: When a leader is elected and asks replicas to sync back to him and that fails, we should ask those nodes to recovery asynchronously rather than synchronously. (Mark Miller) * SOLR-3709: Cache the url list created from the ClusterState in CloudSolrServer on each request. (Mark Miller) Bug Fixes ---------------------- * SOLR-3685: Solr Cloud sometimes skipped peersync attempt and replicated instead due to tlog flags not being cleared when no updates were buffered during a previous replication. (Markus Jelsma, Mark Miller, yonik) * SOLR-3229: Fixed TermVectorComponent to work with distributed search (Hang Xie, hossman) * SOLR-3725: Fixed package-local-src-tgz target to not bring in unnecessary jars and binary contents. (Michael Dodsworth via rmuir) * SOLR-3649: Fixed bug in JavabinLoader that caused deleteById(List ids) to not work in SolrJ (siren) * SOLR-3730: Rollback is not implemented quite right and can cause corner case fails in SolrCloud tests. (rmuir, Mark Miller) * SOLR-2981: Fixed StatsComponent to no longer return duplicated information when requesting multiple stats.facet fields. (Roman Kliewer via hossman) * SOLR-3743: Fixed issues with atomic updates and optimistic concurrency in conjunction with stored copyField targets by making real-time get never return copyField targets. (yonik) * SOLR-3746: Proper error reporting if updateLog is configured w/o necessary "_version_" field in schema.xml (hossman) * SOLR-3745: Proper error reporting if SolrCloud mode is used w/o necessary "_version_" field in schema.xml (hossman) * SOLR-3770: Overseer may lose updates to cluster state (siren) * SOLR-3721: Fix bug that could theoretically allow multiple recoveries to run briefly at the same time if the recovery thread join call was interrupted. (Per Steffensen, Mark Miller) * SOLR-3782: A leader going down while updates are coming in can cause shard inconsistency. (Mark Miller) * SOLR-3611: We do not show ZooKeeper data in the UI for a node that has children. (Mark Miller) * SOLR-3789: Fix bug in SnapPuller that caused "internal" compression to fail. (siren) * SOLR-3790: ConcurrentModificationException could be thrown when using hl.fl=*. Fixed in r1231606. (yonik, koji) * SOLR-3668: DataImport : Specifying Custom Parameters (steffkes) * SOLR-3793: UnInvertedField faceting cached big terms in the filter cache that ignored deletions, leading to duplicate documents in search later when a filter of the same term was specified. (Günter Hipler, hossman, yonik) * SOLR-3679: Core Admin UI gives no feedback if "Add Core" fails (steffkes, hossman) * SOLR-3795: Fixed LukeRequestHandler response to correctly return field name strings in copyDests and copySources arrays (hossman) * SOLR-3699: Fixed some Directory leaks when there were errors during SolrCore or SolrIndexWriter initialization. (hossman) * SOLR-3518: Include final 'hits' in log information when aggregating a distributed request (Markus Jelsma via hossman) * SOLR-3628: SolrInputField and SolrInputDocument are now consistently backed by Collections passed in to setValue/setField, and defensively copy values from Collections passed to addValue/addField (Tom Switzer via hossman) * SOLR-3595: CurrencyField now generates an appropriate error on schema init if it is configured as multiValued - this has never been properly supported, but previously failed silently in odd ways. (hossman) * SOLR-3823: Fix 'bq' parsing in edismax. Please note that this required reverting the negative boost support added by SOLR-3278 (hossman) * SOLR-3827: Fix shareSchema=true in solr.xml (Tomás Fernández Löbbe via hossman) * SOLR-3809: Fixed config file replication when subdirectories are used (Emmanuel Espina via hossman) * SOLR-3828: Fixed QueryElevationComponent so that using 'markExcludes' does not modify the result set or ranking of 'excluded' documents relative to not using elevation at all. (Alexey Serba via hossman) * SOLR-3569: Fixed debug output on distributed requests when there are no results found. (David Bowen via hossman) * SOLR-3811: Query Form using wrong values for dismax, edismax (steffkes) * SOLR-3779: DataImportHandler's LineEntityProcessor when used in conjunction with FileListEntityProcessor would only process the first file. (Ahmet Arslan via James Dyer) * SOLR-3791: CachedSqlEntityProcessor would throw a NullPointerException when a query returns a row with a NULL key. (Steffen Moelter via James Dyer) * SOLR-3833: When a election is started because a leader went down, the new leader candidate should decline if the last state they published was not active. (yonik, Mark Miller) * SOLR-3836: When doing peer sync, we should only count sync attempts that cannot reach the given host as success when the candidate leader is syncing with the replicas - not when replicas are syncing to the leader. (Mark Miller) * SOLR-3835: In our leader election algorithm, if on connection loss we found we did not create our election node, we should retry, not throw an exception. (Mark Miller) * SOLR-3834: A new leader on cluster startup should also run the leader sync process in case there was a bad cluster shutdown. (Mark Miller) * SOLR-3772: On cluster startup, we should wait until we see all registered replicas before running the leader process - or if they all do not come up, N amount of time. (Mark Miller) * SOLR-3756: If we are elected the leader of a shard, but we fail to publish this for any reason, we should clean up and re trigger a leader election. (Mark Miller) * SOLR-3812: ConnectionLoss during recovery can cause lost updates, leading to shard inconsistency. (Mark Miller) * SOLR-3813: When a new leader syncs, we need to ask all shards to sync back, not just those that are active. (Mark Miller) * SOLR-3641: CoreContainer is not persisting roles core attribute.

(Mark Miller) * SOLR-3870: SyncStrategy should have a close so it can abort earlier on shutdown. (Mark Miller) ================== 4.0.0-BETA =================== Versions of Major Components --------------------- Apache Tika 1.1 Carrot2 3.5.0 Velocity 1.6.4 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.3.6 Upgrading from Solr 4.0.0-ALPHA ---------------------- Solr is now much more strict about requiring that the uniqueKeyField feature (if used) must refer to a field which is not multiValued. If you upgrade from an earlier version of Solr and see an error that your uniqueKeyField "can not be configured to be multivalued" please add 'multiValued="false"' to the declaration for your uniqueKeyField. See SOLR-3682 for more details. Detailed Change List ---------------------- New Features ---------------------- * LUCENE-4201: Added JapaneseIterationMarkCharFilterFactory to normalize Japanese iteration marks. (Robert Muir, Christian Moen) * SOLR-1856: In Solr Cell, literals should override Tika-parsed values. Patch adds a param "literalsOverride" which defaults to true, but can be set to "false" to let Tika-parsed values be appended to literal values (Chris Harris, janhoy) * SOLR-3488: Added a Collection management API for SolrCloud. (Tommaso Teofili, Sami Siren, yonik, Mark Miller) * SOLR-3559: Full deleteByQuery support with SolrCloud distributed indexing. All replicas of a shard will be consistent, even if updates arrive in a different order on different replicas. (yonik) * SOLR-1929: Index encrypted documents with ExtractingUpdateRequestHandler. By supplying resource.password= or specifying an external file with regular expressions matching file names, Solr will decrypt and index PDFs and DOCX formats. (janhoy, Yiannis Pericleous) * SOLR-3562: Add options to remove instance dir or data dir on core unload. (Mark Miller, Per Steffensen) * SOLR-2702: The default directory factory was changed to NRTCachingDirectoryFactory which wraps the StandardDirectoryFactory and caches small files for improved Near Real-time (NRT) performance. (Mark Miller, yonik) * SOLR-2616: Include a sample java util logging configuration file. (David Smiley, Mark Miller) * SOLR-3460: Add cloud-scripts directory and a zkcli.sh|bat tool for easy scripting and interaction with ZooKeeper. (Mark Miller) * SOLR-1725: StatelessScriptUpdateProcessorFactory allows users to implement the full ScriptUpdateProcessor API using any scripting language with a javax.script.ScriptEngineFactory (Uri Boness, ehatcher, Simon Rosenthal, hossman) * SOLR-139: Change to updateable documents to create the document if it doesn't already exist. To assert that the document must exist, use the optimistic concurrency feature by specifying a _version_ of 1. (yonik) * LUCENE-2510, LUCENE-4044: Migrated Solr's Tokenizer-, TokenFilter-, and CharFilterFactories to the lucene-analysis module. To add new analysis modules to Solr (like ICU, SmartChinese, Morfologik,...), just drop in the JAR files from Lucene's binary distribution into your Solr instance's lib folder. The factories are automatically made available with SPI. (Chris Male, Robert Muir, Uwe Schindler) * SOLR-3634, SOLR-3635: CoreContainer and CoreAdminHandler will now remember and report back information about failures to initialize SolrCores. These failures will be accessible from the web UI and CoreAdminHandler STATUS command until they are "reset" by creating/renaming a SolrCore with the same name. (hossman, steffkes) * SOLR-1280: Added commented-out example of the new script update processor to the example configuration. See http://wiki.apache.org/solr/ScriptUpdateProcessor (ehatcher) * SOLR-3672: SimplePostTool: Improvements for posting files Support for auto mode, recursive and wildcards (janhoy) Optimizations ---------------------- * SOLR-3708: Add hashCode to ClusterState so that structures built based on the ClusterState can be easily cached. (Mark Miller) * SOLR-3709: Cache the url list created from the ClusterState in CloudSolrServer on each request. (Mark Miller, yonik) * SOLR-3710: Change CloudSolrServer so that update requests are only sent to leaders by default. (Mark Miller) Bug Fixes ---------------------- * SOLR-3582: Our ZooKeeper watchers respond to session events as if they are change events, creating undesirable side effects. (Trym R. Møller, Mark Miller) * SOLR-3467: ExtendedDismax escaping is missing several reserved characters (Michael Dodsworth via janhoy) * SOLR-3587: After reloading a SolrCore, the original Analyzer is still used rather than a new one. (Alexey Serba, yonik, rmuir, Mark Miller) * LUCENE-4185: Fix a bug where CharFilters were wrongly being applied twice. (Michael Froh, rmuir) * SOLR-3610: After reloading a core, indexing would fail on any newly added fields to the schema. (Brent Mills, rmuir) * SOLR-3377: edismax fails to correctly parse a fielded query wrapped by parens. This regression was introduced in 3.6. (Bernd Fehling, Jan Høydahl, yonik) * SOLR-3621: Fix rare concurrency issue when opening a new IndexWriter for replication or rollback. (Mark Miller) * SOLR-1781: Replication index directories not always cleaned up. (Markus Jelsma, Terje Sten Bjerkseth, Mark Miller) * SOLR-3639: Update ZooKeeper to 3.3.6 for a variety of bug fixes. (Mark Miller) * SOLR-3629: Typo in solr.xml persistence when overriding the solrconfig.xml file name using the "config" attribute prevented the override file from being used. (Ryan Zezeski, hossman) * SOLR-3642: Correct broken check for multivalued fields in stats.facet (Yandong Yao, hossman) * SOLR-3660: Velocity: Link to admin page broken (janhoy) * SOLR-3658: Adding thousands of docs with one UpdateProcessorChain instance can briefly create spikes of threads in the thousands. (yonik, Mark Miller) * SOLR-3656: A core reload now always uses the same dataDir. (Mark Miller, yonik) * SOLR-3662: Core reload bugs: a reload always obtained a non-NRT searcher, which could go back in time with respect to the previous core's NRT searcher. Versioning did not work correctly across a core reload, and update handler synchronization was changed to synchronize on core state since more than on update handler can coexist for a single index during a reload. (yonik) * SOLR-3663: There are a couple of bugs in the sync process when a leader goes down and a new leader is elected. (Mark Miller) * SOLR-3623: Fixed inconsistent treatment of third-party dependencies for solr contribs analysis-extras & uima (hossman) * SOLR-3652: Fixed range faceting to error instead of looping infinitely when 'gap' is zero -- or effectively zero due to floating point arithmetic underflow. (hossman) * SOLR-3648: Fixed VelocityResponseWriter template loading in SolrCloud mode. For the example configuration, this means /browse now works with SolrCloud. (janhoy, ehatcher) * SOLR-3677: Fixed misleading error message in web ui to distinguish between no SolrCores loaded vs. no /admin/ handler available. (hossman, steffkes) * SOLR-3428: SolrCmdDistributor flushAdds/flushDeletes can cause repeated adds/deletes to be sent (Mark Miller, Per Steffensen) * SOLR-3647: DistributedQueue should use our Solr zk client rather than the std zk client. ZooKeeper expiration can be permanent otherwise. (Mark Miller) Other Changes ---------------------- * SOLR-3524: Make discarding punctuation configurable in JapaneseTokenizerFactory. The default is to discard punctuation, but this is overridable as an expert option. (Kazuaki Hiraga, Jun Ohtani via Christian Moen) * SOLR-1770: Move the default core instance directory into a collection1 folder. (Mark Miller) * SOLR-3355: Add shard and collection to SolrCore statistics. (Michael Garski, Mark Miller) * SOLR-3575: solr.xml should default to persist=true (Mark Miller) * SOLR-3563: Unloading all cores in a SolrCloud collection will now cause the removal of that collection's meta data from ZooKeeper. (Mark Miller, Per Steffensen) * SOLR-3599: Add zkClientTimeout to solr.xml so that it's obvious how to change it and so that you can change it with a system property. (Mark Miller) * SOLR-3609: Change Solr's expanded webapp directory to be at a consistent path called solr-webapp rather than a temporary directory. (Mark Miller) * SOLR-3600: Raise the default zkClientTimeout from 10 seconds to 15 seconds. (Mark Miller) * SOLR-3215: Clone SolrInputDocument when distrib indexing so that update processors after the distrib update process do not process the document twice. (Mark Miller) * SOLR-3683: Improved error handling if an contains both an explicit class attribute, as well as nested factories. (hossman) * SOLR-3682: Fail to parse schema.xml if uniqueKeyField is multivalued (hossman) * SOLR-2115: DIH no longer requires the "config" parameter to be specified in solrconfig.xml. Instead, the configuration is loaded and parsed with every import. This allows the use of a different configuration with each import, and makes correcting configuration errors simpler. Also, the configuration itself can be passed using the "dataConfig" parameter rather than using a file (this previously worked in debug mode only). When configuration errors are encountered, the error message is returned in XML format. (James Dyer) * SOLR-3439: Make SolrCell easier to use out of the box. Also improves "/browse" to display rich-text documents correctly, along with facets for author and content_type. With the new "content" field, highlighting of body is supported. See also SOLR-3672 for easier posting of a whole directory structure. (Jack Krupansky, janhoy) * SOLR-3579: SolrCloud view should default to the graph view rather than tree view. (steffkes, Mark Miller) ================== 4.0.0-ALPHA ================== More information about this release, including any errata related to the release notes, upgrade instructions, or other changes may be found online at: https://wiki.apache.org/solr/Solr4.0 Versions of Major Components --------------------- Apache Tika 1.1 Carrot2 3.5.0 Velocity 1.6.4 and Velocity Tools 2.0 Apache UIMA 2.3.1 Apache ZooKeeper 3.3.4 Upgrading from Solr 3.6-dev ---------------------- * The Lucene index format has changed and as a result, once you upgrade, previous versions of Solr will no longer be able to read your indices. In a master/slave configuration, all searchers/slaves should be upgraded before the master. If the master were to be updated first, the older searchers would not be able to read the new index format. * Setting abortOnConfigurationError=false is no longer supported (since it has never worked properly). Solr will now warn you if you attempt to set this configuration option at all. (see SOLR-1846) * The default logic for the 'mm' param of the 'dismax' QParser has been changed. If no 'mm' param is specified (either in the query, or as a default in solrconfig.xml) then the effective value of the 'q.op' param (either in the query or as a default in solrconfig.xml or from the 'defaultOperator' option in schema.xml) is used to influence the behavior. If q.op is effectively "AND" then mm=100%. If q.op is effectively "OR" then mm=0%. Users who wish to force the legacy behavior should set a default value for the 'mm' param in their solrconfig.xml file. * The VelocityResponseWriter is no longer built into the core. Its JAR and dependencies now need to be added (via or solr/home lib inclusion), and it needs to be registered in solrconfig.xml like this: * The update request parameter to choose Update Request Processor Chain is renamed from "update.processor" to "update.chain". The old parameter was deprecated but still working since Solr3.2, but is now removed entirely. * The and sections of solrconfig.xml are discontinued and replaced with the section. There are also better defaults. When migrating, if you don't know what your old settings mean, simply delete both and sections. If you have customizations, put them in section - with same syntax as before. * Two of the SolrServer subclasses in SolrJ were renamed/replaced. CommonsHttpSolrServer is now HttpSolrServer, and StreamingUpdateSolrServer is now ConcurrentUpdateSolrServer. * The PingRequestHandler no longer looks for a option in the (legacy) section of solrconfig.xml. Users who wish to take advantage of this feature should configure a "healthcheckFile" init param directly on the PingRequestHandler. As part of this change, relative file paths have been fixed to be resolved against the data dir. See the example solrconfig.xml and SOLR-1258 for more details. * Due to low level changes to support SolrCloud, the uniqueKey field can no longer be populated via or in the schema.xml. Users wishing to have Solr automatically generate a uniqueKey value when adding documents should instead use an instance of solr.UUIDUpdateProcessorFactory in their update processor chain. See SOLR-2796 for more details. Detailed Change List ---------------------- New Features ---------------------- * SOLR-3272: Solr filter factory for MorfologikFilter (Polish lemmatisation). (Rafał Kuć via Dawid Weiss, Steven Rowe, Uwe Schindler). * SOLR-571: The autowarmCount for LRUCaches (LRUCache and FastLRUCache) now supports "percentages" which get evaluated relative the current size of the cache when warming happens. (Tomás Fernández Löbbe and hossman) * SOLR-1932: New relevancy function queries: termfreq, tf, docfreq, idf norm, maxdoc, numdocs. (yonik) * SOLR-1665: Add debug component options for timings, results and query info only (gsingers, hossman, yonik) * SOLR-2112: Solrj API now supports streaming results. (ryan) * SOLR-792: Adding PivotFacetComponent for Hierarchical faceting (ehatcher, Jeremy Hinegardner, Thibaut Lassalle, ryan) * LUCENE-2507, SOLR-2571, SOLR-2576: Added DirectSolrSpellChecker, which uses Lucene's DirectSpellChecker to retrieve correction candidates directly from the term dictionary using levenshtein automata. (James Dyer, rmuir) * SOLR-1873, SOLR-2358: SolrCloud - added shared/central config and core/shard management via zookeeper, built-in load balancing, and distributed indexing. (Jamie Johnson, Sami Siren, Ted Dunning, yonik, Mark Miller) Additional Work: - SOLR-2324: SolrCloud solr.xml parameters are not persisted by CoreContainer. (Massimo Schiavon, Mark Miller) - SOLR-2287: Allow users to query by multiple, compatible collections with SolrCloud. (Soheb Mahmood, Alex Cowell, Mark Miller) - SOLR-2622: ShowFileRequestHandler does not work in SolrCloud mode. (Stefan Matheis, Mark Miller) - SOLR-3108: Error in SolrCloud's replica lookup code when replica's are hosted in same Solr instance. (Bruno Dumon, Sami Siren, Mark Miller) - SOLR-3080: Remove shard info from zookeeper when SolrCore is explicitly unloaded. (yonik, Mark Miller, siren) - SOLR-3437: Recovery issues a spurious commit to the cluster. (Trym R. Møller via Mark Miller) - SOLR-2822: Skip update processors already run on other nodes (hossman) * SOLR-1566: Transforming documents in the ResponseWriters. This will allow for more complex results in responses and open the door for function queries as results. (ryan with patches from grant, noble, cmale, yonik, Jan Høydahl, Arul Kalaipandian, Luca Cavanna, hossman) - SOLR-2037: Thanks to SOLR-1566, documents boosted by the QueryElevationComponent can be marked as boosted. (gsingers, ryan, yonik) * SOLR-2396: Add CollationField, which is much more efficient than the Solr 3.x CollationKeyFilterFactory, and also supports Locale-sensitive range queries. (rmuir) * SOLR-2338: Add support for using in a schema's fieldType, for customizing scoring on a per-field basis. (hossman, yonik, rmuir) * SOLR-2335: New 'field("...")' function syntax for referring to complex field names (containing whitespace or special characters) in functions. * SOLR-2383: /browse improvements: generalize range and date facet display (Jan Høydahl via yonik) * SOLR-2272: Pseudo-join queries / filters. Examples: - To restrict to the set of parents with at least one blue-eyed child: fq={!join from=parent to=name}eyes:blue - To restrict to the set of children with at least one blue-eyed parent: fq={!join from=name to=parent}eyes:blue (yonik) * SOLR-1942: Added the ability to select postings format per fieldType in schema.xml as well as support custom Codecs in solrconfig.xml. (simonw via rmuir) * SOLR-2136: Boolean type added to function queries, along with new functions exists(), if(), and(), or(), xor(), not(), def(), and true and false constants. (yonik) * SOLR-2491: Add support for using spellcheck collation in conjunction with grouping. Note that the number of hits returned for collations is the number of ungrouped hits. (James Dyer via rmuir) * SOLR-1298: Return FunctionQuery as pseudo field. The solr 'fl' param now supports functions. For example: fl=id,sum(x,y) -- NOTE: only functions with fast random access are recommended. (yonik, ryan) * SOLR-705: Optionally return shard info with each document in distributed search. Use fl=id,[shard] to return the shard url. (ryan) * SOLR-2417: Add explain info directly to return documents using ?fl=id,[explain] (ryan) * SOLR-2533: Converted ValueSource.ValueSourceSortField over to new rewriteable Lucene SortFields. ValueSourceSortField instances must be rewritten before they can be used. This is done by SolrIndexSearcher when necessary. (Chris Male). * SOLR-2193, SOLR-2565: You may now specify a 'soft' commit when committing. This will use Lucene's NRT feature to avoid guaranteeing documents are on stable storage in exchange for faster reopen times. There is also a new 'soft' autocommit tracker that can be configured. (Mark Miller, Robert Muir) * SOLR-2399: Updated Solr Admin interface. New look and feel with per core administration and many new options. (Stefan Matheis via ryan) * SOLR-1032: CSV handler now supports "literal.field_name=value" parameters. (Simon Rosenthal, ehatcher) * SOLR-2656: realtime-get, efficiently retrieves the latest stored fields for specified documents, even if they are not yet searchable (i.e. without reopening a searcher) (yonik) * SOLR-2703: Added support for Lucene's "surround" query parser. (Simon Rosenthal, ehatcher) * SOLR-2754: Added factories for several ranking algorithms: - BM25SimilarityFactory: Okapi BM25 - DFRSimilarityFactory: Divergence from Randomness models - IBSimilarityFactory: Information-based models - LMDirichletSimilarity: LM with Dirichlet smoothing - LMJelinekMercerSimilarity: LM with Jelinek-Mercer smoothing (David Mark Nemeskey, Robert Muir) * SOLR-2134 Trie* fields should support sortMissingLast=true, and deprecate Sortable* Field Types (Ryan McKinley, Mike McCandless, Uwe Schindler, Erick Erickson) * SOLR-2438 added MultiTermAwareComponent to the various classes to allow automatic lowercasing for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a "multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't specify (Pete Sturge Erick Erickson, Mentoring from Seeley and Muir) * SOLR-2481: Add support for commitWithin in DataImportHandler (Sami Siren via yonik) * SOLR-2992: Add support for IndexWriter.prepareCommit() via prepareCommit=true on update URLs. (yonik) * SOLR-2906: Added LFU cache options to Solr. (Shawn Heisey via Erick Erickson) * SOLR-3069: Ability to add openSearcher=false to not open a searcher when doing a hard commit. commitWithin now only invokes a softCommit. (yonik) * SOLR-2802: New FieldMutatingUpdateProcessor and Factory to simplify the development of UpdateProcessors that modify field values of documents as they are indexed. Also includes several useful new implementations: - RemoveBlankFieldUpdateProcessorFactory - TrimFieldUpdateProcessorFactory - HTMLStripFieldUpdateProcessorFactory - RegexReplaceProcessorFactory - FieldLengthUpdateProcessorFactory - ConcatFieldUpdateProcessorFactory - FirstFieldValueUpdateProcessorFactory - LastFieldValueUpdateProcessorFactory - MinFieldValueUpdateProcessorFactory - MaxFieldValueUpdateProcessorFactory - TruncateFieldUpdateProcessorFactory - IgnoreFieldUpdateProcessorFactory (hossman, janhoy) * SOLR-3120: Optional post filtering for spatial queries bbox and geofilt for LatLonType. (yonik) * SOLR-2459: Expose LogLevel selection with a RequestHandler rather then servlet (Stefan Matheis, Upayavira, ryan) * SOLR-3134: Include shard info in distributed response when shards.info=true (Russell Black, ryan) * SOLR-2898: Support grouped faceting. (Martijn van Groningen) Additional Work: - SOLR-3406: Extended grouped faceting support to facet.query and facet.range parameters. (David Boychuck, Martijn van Groningen) * SOLR-2949: QueryElevationComponent is now supported with distributed search. (Mark Miller, yonik) * SOLR-3221: Added the ability to directly configure aspects of the concurrency and thread-pooling used within distributed search in solr. This allows for finer grained controlled and can be tuned by end users to target their own specific requirements. This builds on the work of the HttpCommComponent and uses the same configuration block to configure the thread pool. The default configuration has the same behaviour as solr 3.5, favouring throughput over latency. More information can be found on the wiki (http://wiki.apache.org/solr/SolrConfigXml) (Greg Bowyer) * SOLR-3278: Negative boost support to the Extended Dismax Query Parser Boost Query (bq). (James Dyer) * SOLR-3255: OpenExchangeRates.Org Exchange Rate Provider for CurrencyField (janhoy) * SOLR-3358: Logging events are captured and available from the /admin/logging request handler. (ryan) * SOLR-1535: PreAnalyzedField type provides a functionality to index (and optionally store) field content that was already processed and split into tokens using some external processing chain. Serialization format is pluggable, and defaults to JSON. (ab) * SOLR-3363: Consolidated Exceptions in Analysis Factories so they only throw InitializationExceptions (Chris Male) * SOLR-2690: New support for a "TZ" request param which overrides the TimeZone used when rounding Dates in DateMath expressions for the entire request (all date range queries and date faceting is affected). The default TZ is still UTC. (David Schlotfeldt, hossman) * SOLR-3402: Analysis Factories are now configured with their Lucene Version throw setLuceneMatchVersion, rather than through the Map passed to init. Parsing and simple error checking for the Version is now done inside the code that creates the Analysis Factories. (Chris Male) * SOLR-3178: Optimistic locking. If a _version_ is provided with an update that does not match the version in the index, an HTTP 409 error (Conflict) will result. (Per Steffensen, yonik) * SOLR-139: Updateable documents. JSON Example: {"id":"mydoc", "f1":{"set":10}, "f2":{"add":20}} will result in field "f1" being set to 10, "f2" having an additional value of 20 added, and all other existing fields unchanged. All source fields must be stored for this feature to work correctly. (Ryan McKinley, Erik Hatcher, yonik) * SOLR-2857: Support XML,CSV,JSON, and javabin in a single RequestHandler and choose the correct ContentStreamLoader based on Content-Type header. This also deprecates the existing [Xml,JSON,CSV,Binary,Xslt]UpdateRequestHandler. (ryan) * SOLR-2585: Context-Sensitive Spelling Suggestions & Collations. This adds support for the "spellcheck.alternativeTermCount" & "spellcheck.maxResultsForSuggest" parameters, letting users receive suggestions even when all the queried terms exist in the dictionary. This differs from "spellcheck.onlyMorePopular" in that the suggestions need not consist entirely of terms with a greater document frequency than the queried terms. (James Dyer) * SOLR-2058: Edismax query parser to allow "phrase slop" to be specified per-field on the pf/pf2/pf3 parameters using optional "FieldName~slop^boost" syntax. The prior "FieldName^boost" syntax is still accepted. In such cases the value on the "ps" parameter serves as the default slop. (Ron Mayer via James Dyer) * SOLR-3495: New UpdateProcessors have been added to create default values for configured fields. These works similarly to the option in schema.xml, but are applied in the UpdateProcessorChain, so they may be used prior to other UpdateProcessors, or to generate a uniqueKey field value when using the DistributedUpdateProcessor (ie: SolrCloud) TimestampUpdateProcessorFactory UUIDUpdateProcessorFactory DefaultValueUpdateProcessorFactory (hossman) * SOLR-2993: Add WordBreakSolrSpellChecker to offer suggestions by combining adjacent query terms and/or breaking terms into multiple words. This spellchecker can be configured with a traditional checker (ie: DirectSolrSpellChecker). The results are combined and collations can contain a mix of corrections from both spellcheckers. (James Dyer) * SOLR-3508: Simplify JSON update format for deletes as well as allow version specification for optimistic locking. Examples: - {"delete":"myid"} - {"delete":["id1","id2","id3"]} - {"delete":{"id":"myid", "_version_":123456789}} (yonik) * SOLR-3211: Allow parameter overrides in conjunction with "spellcheck.maxCollationTries". To do so, use parameters starting with "spellcheck.collateParam." For instance, to override the "mm" parameter, specify "spellcheck.collateParam.mm". This is helpful in cases where testing spellcheck collations for result counts should use different parameters from the main query (James Dyer) * SOLR-2599: CloneFieldUpdateProcessorFactory provides similar functionality to schema.xml's declaration but as an update processor that can be combined with other processors in any order. (Jan Høydahl & hossman) * SOLR-3351: eDismax: ps2 and ps3 params (janhoy) * SOLR-3542: Add WeightedFragListBuilder for FVH and set it to default fragListBuilder in example solrconfig.xml. (Sebastian Lutze, koji) * SOLR-2396: Add ICUCollationField to contrib/analysis-extras, which is much more efficient than the Solr 3.x ICUCollationKeyFilterFactory, and also supports Locale-sensitive range queries. (rmuir) Optimizations ---------------------- * SOLR-1875: Per-segment field faceting for single valued string fields. Enable with facet.method=fcs, control the number of threads used with the "threads" local param on the facet.field param. This algorithm will only be faster in the presence of rapid index changes. (yonik) * SOLR-1904: When facet.enum.cache.minDf > 0 and the base doc set is a SortedIntSet, convert to HashDocSet for better performance. (yonik) * SOLR-2092: Speed up single-valued and multi-valued "fc" faceting. Typical improvement is 5%, but can be much greater (up to 10x faster) when facet.offset is very large (deep paging). (yonik) * SOLR-2193, SOLR-2565: The default Solr update handler has been improved so that it uses fewer locks, keeps the IndexWriter open rather than closing it on each commit (ie commits no longer wait for background merges to complete), works with SolrCore to provide faster 'soft' commits, and has an improved API that requires less instanceof special casing. (Mark Miller, Robert Muir) Additional Work: - SOLR-2697: commit and autocommit operations don't reset DirectUpdateHandler2.numDocsPending stats attribute. (Alexey Serba, Mark Miller) * SOLR-2950: The QueryElevationComponent now avoids using the FieldCache and looking up every document id (gsingers, yonik) Bug Fixes ---------------------- * SOLR-3139: Make ConcurrentUpdateSolrServer send UpdateRequest.getParams() as HTTP request params (siren) * SOLR-3165: Cannot use DIH in Solrcloud + Zookeeper (Alexey Serba, Mark Miller, siren) * SOLR-3068: Occasional NPE in ThreadDumpHandler (siren) * SOLR-2762: FSTLookup could return duplicate results or one results less than requested. (David Smiley, Dawid Weiss) * SOLR-2741: Bugs in facet range display in trunk (janhoy) * SOLR-1908: Fixed SignatureUpdateProcessor to fail to initialize on invalid config. Specifically: a signatureField that does not exist, or overwriteDupes=true with a signatureField that is not indexed. (hossman) * SOLR-1824: IndexSchema will now fail to initialize if there is a problem initializing one of the fields or field types. (hossman) * SOLR-1928: TermsComponent didn't correctly break ties for non-text fields sorted by count. (yonik) * SOLR-2107: MoreLikeThisHandler doesn't work with alternate qparsers. (yonik) * SOLR-2108: Fixed false positives when using wildcard queries on fields with reversed wildcard support. For example, a query of *zemog* would match documents that contain 'gomez'. (Landon Kuhn via Robert Muir) * SOLR-1962: SolrCore#initIndex should not use a mix of indexPath and newIndexPath (Mark Miller) * SOLR-2275: fix DisMax 'mm' parsing to be tolerant of whitespace (Erick Erickson via hossman) * SOLR-2193, SOLR-2565, SOLR-2651: SolrCores now properly share IndexWriters across SolrCore reloads. (Mark Miller, Robert Muir) Additional Work: - SOLR-2705: On reload, IndexWriterProvider holds onto the initial SolrCore it was created with. (Yury Kats, Mark Miller) * SOLR-2682: Remove addException() in SimpleFacet. FacetComponent no longer catches and embeds exceptions occurred during facet processing, it throws HTTP 400 or 500 exceptions instead. (koji) * SOLR-2654: Directorys used by a SolrCore are now closed when they are no longer used. (Mark Miller) * SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling, rather than loading URL content streams automatically regardless of use. (David Smiley and Ryan McKinley via ehatcher) * SOLR-2829: Fix problem with false-positives due to incorrect equals methods. (Yonik Seeley, Hossman, Erick Erickson. Marc Tinnemeyer caught the bug) * SOLR-2848: Removed 'instanceof AbstractLuceneSpellChecker' hacks from distributed spellchecking code, and added a merge() method to SolrSpellChecker instead. Previously if you extended SolrSpellChecker your spellchecker would not work in distributed fashion. (James Dyer via rmuir) * SOLR-2509: StringIndexOutOfBoundsException in the spellchecker collate when the term contains a hyphen. (Thomas Gambier caught the bug, Steffen Godskesen did the patch, via Erick Erickson) * SOLR-1730: Made it clearer when a core failed to load as well as better logging when the QueryElevationComponent fails to properly initialize (gsingers) * SOLR-1520: QueryElevationComponent now supports non-string ids (gsingers) * SOLR-3037: When using binary format in solrj the codec screws up parameters (Sami Siren, Jörg Maier via yonik) * SOLR-3062: A join in the main query was not respecting any filters pushed down to it via acceptDocs since LUCENE-1536. (Mike Hugo, yonik) * SOLR-3214: If you use multiple fl entries rather than a comma separated list, all but the first entry can be ignored if you are using distributed search. (Tomás Fernández Löbbe via Mark Miller) * SOLR-3352: eDismax: pf2 should kick in for a query with 2 terms (janhoy) * SOLR-3361: ReplicationHandler "maxNumberOfBackups" doesn't work if backups are triggered on commit (James Dyer, Tomás Fernández Löbbe) * SOLR-2605: fixed tracking of the 'defaultCoreName' in CoreContainer so that CoreAdminHandler could return consistent information regardless of whether there is a a default core name or not. (steffkes, hossman) * SOLR-3370: fixed CSVResponseWriter to respect globs in the 'fl' param (Keith Fligg via hossman) * SOLR-3436: Group count incorrect when not all shards are queried in the second pass. (Francois Perron, Martijn van Groningen) * SOLR-3454: Exception when using result grouping with main=true and using wt=javabin. (Ludovic Boutros, Martijn van Groningen) * SOLR-3446: Better errors when PatternTokenizerFactory is configured with an invalid pattern, and include the 'name' whenever possible in plugin init error messages. (hossman) * LUCENE-4075: Cleaner path usage in TestXPathEntityProcessor (Greg Bowyer via hossman) * SOLR-2923: IllegalArgumentException when using useFilterForSortedQuery on an empty index. (Adrien Grand via Mark Miller) * SOLR-2352: Fixed TermVectorComponent so that it will not fail if the fl param contains globs or psuedo-fields (hossman) * SOLR-3541: add missing solrj dependencies to binary packages. (Thijs Vonk via siren) * SOLR-3522: fixed parsing of the 'literal()' function (hossman) * SOLR-3548: Fixed a bug in the cachability of queries using the {!join} parser or the strdist() function, as well as some minor improvements to the hashCode implementation of {!bbox} and {!geofilt} queries. (hossman) * SOLR-3470: contrib/clustering: custom Carrot2 tokenizer and stemmer factories are respected now (Stanislaw Osinski, Dawid Weiss) * SOLR-3430: Added a new DIH test against a real SQL database. Fixed problems revealed by this new test related to the expanded cache support added to 3.6/SOLR-2382 (James Dyer) * SOLR-1958: When using the MailEntityProcessor, import would fail if fetchMailsSince was not specified. (Max Lynch via James Dyer) * SOLR-4289: Admin UI - JVM memory bar - dark grey "used" width is too small (steffkes, elyograg) Other Changes ---------------------- * SOLR-1846: Eliminate support for the abortOnConfigurationError option. It has never worked very well, and in recent versions of Solr hasn't worked at all. (hossman) * SOLR-1889: The default logic for the 'mm' param of DismaxQParser and ExtendedDismaxQParser has been changed to be determined based on the effective value of the 'q.op' param (hossman) * SOLR-1946: Misc improvements to the SystemInfoHandler: /admin/system (hossman) * SOLR-2289: Tweak spatial coords for example docs so they are a bit more spread out (Erick Erickson via hossman) * SOLR-2288: Small tweaks to eliminate compiler warnings. primarily using Generics where applicable in method/object declarations, and adding @SuppressWarnings("unchecked") when appropriate (hossman) * SOLR-2375: Suggester Lookup implementations now store trie data and load it back on init. This means that large tries don't have to be rebuilt on every commit or core reload. (ab) * SOLR-2413: Support for returning multi-valued fields w/o tag in the XMLResponseWriter was removed. XMLResponseWriter only no longer work with values less then 2.2 (ryan) * SOLR-2423: FieldType argument changed from String to Object Conversion from SolrInputDocument > Object > Fieldable is now managed by FieldType rather then DocumentBuilder. (ryan) * SOLR-2461: QuerySenderListener and AbstractSolrEventListener are now public (hossman) * LUCENE-2995: Moved some spellchecker and suggest APIs to modules/suggest: HighFrequencyDictionary, SortedIterator, TermFreqIterator, and the suggester APIs and implementations. (rmuir) * SOLR-2576: Remove deprecated SpellingResult.add(Token, int). (James Dyer via rmuir) * LUCENE-3232: Moved MutableValue classes to new 'common' module. (Chris Male) * LUCENE-2883: FunctionQuery, DocValues (and its impls), ValueSource (and its impls) and BoostedQuery have been consolidated into the queries module. They can now be found at o.a.l.queries.function. * SOLR-2027: FacetField.getValues() now returns an empty list if there are no values, instead of null (Chris Male) * SOLR-1825: SolrQuery.addFacetQuery now enables facets automatically, like addFacetField (Chris Male) * SOLR-2663: FieldTypePluginLoader has been refactored out of IndexSchema and made public. (hossman) * SOLR-2331,SOLR-2691: Refactor CoreContainer's SolrXML serialization code and improve testing (Yury Kats, hossman, Mark Miller) * SOLR-2698: Enhance CoreAdmin STATUS command to return index size. (Yury Kats, hossman, Mark Miller) * SOLR-2654: The same Directory instance is now always used across a SolrCore so that it's easier to add other DirectoryFactory's without static caching hacks. (Mark Miller) * LUCENE-3286: 'luke' ant target has been disabled due to incompatibilities with XML queryparser location (Chris Male) * SOLR-1897: The data dir from the core descriptor should override the data dir from the solrconfig.xml rather than the other way round. (Mark Miller) * SOLR-2756: Maven configuration: Excluded transitive stax:stax-api dependency from org.codehaus.woodstox:wstx-asl dependency. (David Smiley via Steve Rowe) * SOLR-2588: Moved VelocityResponseWriter back to contrib module in order to remove it as a mandatory core dependency. (ehatcher) * SOLR-2862: More explicit lexical resources location logged if Carrot2 clustering extension is used. Fixed solr. impl. of IResource and IResourceLookup. (Dawid Weiss) * SOLR-1123: Changed JSONResponseWriter to now use application/json as its Content-Type by default. However the Content-Type can be overwritten and is set to text/plain in the example configuration. (Uri Boness, Chris Male) * SOLR-2607: Removed deprecated client/ruby directory, which included solr-ruby and flare. (ehatcher) * SOLR-3032: logOnce from SolrException logOnce and all the supporting structure is gone. abortOnConfigurationError is also gone as it is no longer referenced. Errors should be caught and logged at the top-most level or logged and NOT propagated up the chain. (Erick Erickson) * SOLR-2105: Remove support for deprecated "update.processor" (since 3.2), in favor of "update.chain" (janhoy) * SOLR-3005: Default QueryResponseWriters are now initialized via init() with an empty NamedList. (Gasol Wu, Chris Male) * SOLR-2607: Removed obsolete client/ folder (ehatcher, Eric Pugh, janhoy) * SOLR-3202, SOLR-3244: Dropping Support for JSP. New Admin UI is all client side (ryan, Aliaksandr Zhuhrou, Uwe Schindler) * SOLR-3159: Upgrade example and tests to run with Jetty 8 (ryan) * SOLR-3254: Upgrade Solr to Tika 1.1 (janhoy) * SOLR-3329: Dropped getSourceID() from SolrInfoMBean and using getClass().getPackage().getSpecificationVersion() for Version. (ryan) * SOLR-3302: Upgraded SLF4j to version 1.6.4 (hossman) * SOLR-3322: Add more context to IndexReaderFactory.newReader (ab) * SOLR-3343: Moved FastWriter, FileUtils, RegexFileFilter, RTimer and SystemIdResolver from org.apache.solr.common to org.apache.solr.util (Chris Male) * SOLR-3357: ResourceLoader.newInstance now accepts a Class representation of the expected instance type (Chris Male) * SOLR-3388: HTTP caching is now disabled by default for RequestUpdateHandlers. (ryan) * SOLR-3309: web.xml now specifies metadata-complete=true (which requires Servlet 2.5) to prevent servlet containers from scanning class annotations on startup. This allows for faster startup times on some servlet containers. (Bill Bell, hossman) * SOLR-1893: Refactored some common code from LRUCache and FastLRUCache into SolrCacheBase (Tomás Fernández Löbbe via hossman) * SOLR-3403: Deprecated Analysis Factories now log their own deprecation messages. No logging support is provided by Factory parent classes. (Chris Male) * SOLR-1258: PingRequestHandler is now directly configured with a "healthcheckFile" instead of looking for the legacy syntax. Filenames specified as relative paths have been fixed so that they are resolved against the data dir instead of the CWD of the java process. (hossman) * SOLR-3083: JMX beans now report Numbers as numeric values rather then String (Tagged Siteops, Greg Bowyer via ryan) * SOLR-2796: Due to low level changes to support SolrCloud, the uniqueKey field can no longer be populated via or in the schema.xml. * SOLR-3534: The Dismax and eDismax query parsers will fall back on the 'df' parameter when 'qf' is absent. And if neither is present nor the schema default search field then an exception will be thrown now. (dsmiley) * SOLR-3262: The "threads" feature of DIH is removed (deprecated in Solr 3.6) (James Dyer) * SOLR-3422: Refactored DIH internal data classes. All entities in data-config.xml must have a name (James Dyer) Documentation ---------------------- * SOLR-2232: Improved README info on solr.solr.home in examples (Eric Pugh and hossman) ================== 3.6.2 ================== Bug Fixes ---------------------- * SOLR-3790: ConcurrentModificationException could be thrown when using hl.fl=*. (yonik, koji) * SOLR-3589: Edismax parser does not honor mm parameter if analyzer splits a token. (Tom Burton-West, Robert Muir) ================== 3.6.1 ================== More information about this release, including any errata related to the release notes, upgrade instructions, or other changes may be found online at: https://wiki.apache.org/solr/Solr3.6.1 Bug Fixes * LUCENE-3969: Throw IAE on bad arguments that could cause confusing errors in PatternTokenizer. CommonGrams populates PositionLengthAttribute correctly. (Uwe Schindler, Mike McCandless, Robert Muir) * SOLR-3361: ReplicationHandler "maxNumberOfBackups" doesn't work if backups are triggered on commit (James Dyer, Tomás Fernández Löbbe) * SOLR-3375: Fix charset problems with HttpSolrServer (Roger Håkansson, yonik, siren) * SOLR-3436: Group count incorrect when not all shards are queried in the second pass. (Francois Perron, Martijn van Groningen) * SOLR-3454: Exception when using result grouping with main=true and using wt=javabin. (Ludovic Boutros, Martijn van Groningen) * SOLR-3489: Config file replication less error prone (Jochen Just via janhoy) * SOLR-3477: SOLR does not start up when no cores are defined (Tomás Fernández Löbbe via tommaso) * SOLR-3470: contrib/clustering: custom Carrot2 tokenizer and stemmer factories are respected now (Stanislaw Osinski, Dawid Weiss) * SOLR-3360: More DIH bug fixes for the deprecated "threads" parameter. (Mikhail Khludnev, Claudio R, via James Dyer) * SOLR-3430: Added a new DIH test against a real SQL database. Fixed problems revealed by this new test related to the expanded cache support added to 3.6/SOLR-2382 (James Dyer) * SOLR-3336: SolrEntityProcessor substitutes most variables at query time. (Michael Kroh, Lance Norskog, via Martijn van Groningen) ================== 3.6.0 ================== More information about this release, including any errata related to the release notes, upgrade instructions, or other changes may be found online at: https://wiki.apache.org/solr/Solr3.6 Upgrading from Solr 3.5 ---------------------- * SOLR-2983: As a consequence of moving the code which sets a MergePolicy from SolrIndexWriter to SolrIndexConfig, (custom) MergePolicies should now have an empty constructor; thus an IndexWriter should not be passed as constructor parameter but instead set using the setIndexWriter() method. * As doGet() methods in SimplePostTool was changed to static, the client applications of this class need to be recompiled. * In Solr version 3.5 and earlier, HTMLStripCharFilter had known bugs in the character offsets it provided, triggering e.g. exceptions in highlighting. HTMLStripCharFilter has been re-implemented, addressing this and other issues. See the entry for LUCENE-3690 in the Bug Fixes section below for a detailed list of changes. For people who depend on the behavior of HTMLStripCharFilter in Solr version 3.5 and earlier: the old implementation (bugs and all) is preserved as LegacyHTMLStripCharFilter. * As of Solr 3.6, the and sections of solrconfig.xml are deprecated and replaced with a new section. Read more in SOLR-1052 below. * SOLR-3040: The DIH's admin UI (dataimport.jsp) now requires DIH request handlers to start with a '/'. (dsmiley) * SOLR-3161: is now the default. An existing config will probably work as-is because handleSelect was explicitly enabled in default configs. HandleSelect makes /select work as well as enables the 'qt' parameter. Instead, consider explicitly configuring /select as is done in the example solrconfig.xml, and register your other search handlers with a leading '/' which is a recommended practice. (David Smiley, Erik Hatcher) * SOLR-3161: Don't use the 'qt' parameter with a leading '/'. It probably won't work in 4.0 and it's now limited in 3.6 to SearchHandler subclasses that aren't lazy-loaded. * SOLR-2724: Specifying and in schema.xml is now considered deprecated. Instead you are encouraged to specify these via the "df" and "q.op" parameters in your request handler definition. (David Smiley) * Bugs found and fixed in the SignatureUpdateProcessor that previously caused some documents to produce the same signature even when the configured fields contained distinct (non-String) values. Users of SignatureUpdateProcessor are strongly advised that they should re-index as document signatures may have now changed. (see SOLR-3200 & SOLR-3226 for details) New Features ---------------------- * SOLR-2020: Add Java client that uses Apache Http Components http client (4.x). (Chantal Ackermann, Ryan McKinley, Yonik Seeley, siren) * SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling, rather than loading URL content streams automatically regardless of use. (David Smiley and Ryan McKinley via ehatcher) * SOLR-2904: BinaryUpdateRequestHandler should be able to accept multiple update requests from a stream (shalin) * SOLR-1565: StreamingUpdateSolrServer supports RequestWriter API and therefore, javabin update format (shalin) * SOLR-2438 added MultiTermAwareComponent to the various classes to allow automatic lowercasing for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a "multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't specify (Pete Sturge Erick Erickson, Mentoring from Seeley and Muir) * SOLR-2919: Added support for localized range queries when the analysis chain uses CollationKeyFilter or ICUCollationKeyFilter. (Michael Sokolov, rmuir) * SOLR-2982: Added BeiderMorseFilterFactory for Beider-Morse (BMPM) phonetic encoder. Upgrades commons-codec to version 1.6 (Brooke Schreier Ganz, rmuir) * SOLR-1843: A new "rootName" attribute is now available when configuring in solrconfig.xml. If this attribute is set, Solr will use it as the root name for all MBeans Solr exposes via JMX. The default root name is "solr" followed by the core name. (Constantijn Visinescu, hossman) * SOLR-2906: Added LFU cache options to Solr. (Shawn Heisey via Erick Erickson) * SOLR-3036: Ability to specify overwrite=false on the URL for XML updates. (Sami Siren via yonik) * SOLR-2603: Add the encoding function for alternate fields in highlighting. (Massimo Schiavon, koji) * SOLR-1729: Evaluation of NOW for date math is done only once per request for consistency, and is also propagated to shards in distributed search. Adding a parameter NOW= to the request will override the current time. (Peter Sturge, yonik, Simon Willnauer) * SOLR-1709: Distributed support for Date and Numeric Range Faceting (Peter Sturge, David Smiley, hossman, Simon Willnauer) * SOLR-3054, LUCENE-3671: Add TypeTokenFilterFactory that creates TypeTokenFilter that filters tokens based on their TypeAttribute. (Tommaso Teofili via Uwe Schindler) * LUCENE-3305, SOLR-3056: Added Kuromoji morphological analyzer for Japanese. See the 'text_ja' fieldtype in the example to get started. (Christian Moen, Masaru Hasegawa via Robert Muir) * SOLR-1860: StopFilterFactory, CommonGramsFilterFactory, and CommonGramsQueryFilterFactory can optionally read stopwords in Snowball format (specify format="snowball"). (Robert Muir) * SOLR-3105: ElisionFilterFactory optionally allows the parameter ignoreCase (default=false). (Robert Muir) * LUCENE-3714: Add WFSTLookupFactory, a suggester that uses a weighted FST for more fine-grained suggestions. (Mike McCandless, Dawid Weiss, Robert Muir) * SOLR-3143: Add SuggestQueryConverter, a QueryConverter intended for auto-suggesters. (Robert Muir) * SOLR-3033: ReplicationHandler's backup command now supports a 'maxNumberOfBackups' init param that can be used to delete all but the most recent N backups. (Torsten Krah, James Dyer) * SOLR-2202: Currency FieldType, whith support for currencies and exchange rates (Greg Fodor & Andrew Morrison via janhoy, rmuir, Uwe Schindler) * SOLR-3026: eDismax: Locking down which fields can be explicitly queried (user fields aka uf) (janhoy, hossmann, Tomás Fernández Löbbe) * SOLR-2826: URLClassify Update Processor (janhoy) * SOLR-2764: Create a NorwegianLightStemmer and NorwegianMinimalStemmer (janhoy) * SOLR-3221: Added the ability to directly configure aspects of the concurrency and thread-pooling used within distributed search in solr. This allows for finer grained controlled and can be tuned by end users to target their own specific requirements. This builds on the work of the HttpCommComponent and uses the same configuration block to configure the thread pool. The default configuration has the same behaviour as solr 3.5, favouring throughput over latency. More information can be found on the wiki (http://wiki.apache.org/solr/SolrConfigXml) (Greg Bowyer) * SOLR-2001: The query component will substitute an empty query that matches no documents if the query parser returns null. This also prevents an exception from being thrown by the default parser if "q" is missing. (yonik) - SOLR-435: if q is "" then it's also acceptable. (dsmiley, hoss) * SOLR-2919: Added parametric tailoring options to ICUCollationKeyFilterFactory. These can be used to customize range query/sort behavior, for example to support numeric collation, ignore punctuation/whitespace, ignore accents but not case, control whether upper/lowercase values are sorted first, etc. (rmuir) * SOLR-2346: Add a chance to set content encoding explicitly via content type of stream for extracting request handler. This is convenient when Tika's auto detector cannot detect encoding, especially the text file is too short to detect encoding. (koji) * SOLR-1499: Added SolrEntityProcessor that imports data from another Solr core or instance based on a specified query. (Lance Norskog, Erik Hatcher, Pulkit Singhal, Ahmet Arslan, Luca Cavanna, Martijn van Groningen) * SOLR-3190: Minor improvements to SolrEntityProcessor. Add more consistency between solr parameters and parameters used in SolrEntityProcessor and ability to specify a custom HttpClient instance. (Luca Cavanna via Martijn van Groningen) * SOLR-2382: Added pluggable cache support to DIH so that any Entity can be made cache-able by adding the "cacheImpl" parameter. Include "SortedMapBackedCache" to provide in-memory caching (as previously this was the only option when using CachedSqlEntityProcessor). Users can provide their own implementations of DIHCache for other caching strategies. Deprecate CachedSqlEntityProcessor in favor of specifing "cacheImpl" with SqlEntityProcessor. Make SolrWriter implement DIHWriter and allow the possibility of pluggable Writers (DIH writing to something other than Solr). (James Dyer, Noble Paul) Optimizations ---------------------- * SOLR-1931: Speedup for LukeRequestHandler and admin/schema browser. New parameter reportDocCount defaults to 'false'. Old behavior still possible by specifying this as 'true' (Erick Erickson) * SOLR-3012: Move System.getProperty("type") in postData() to main() and add type argument so that the client applications of SimplePostTool can set content type via method argument. (koji) * SOLR-2888: FSTSuggester refactoring: internal storage is now UTF-8, external sorting (on disk) prevents OOMs even with large data sets (the bottleneck is now FST construction), code cleanups and API cleanups. (Dawid Weiss, Robert Muir) Bug Fixes ---------------------- * SOLR-3187 SystemInfoHandler leaks filehandles (siren) * LUCENE-3820: Fixed invalid position indexes by reimplementing PatternReplaceCharFilter. This change also drops real support for boundary characters -- all input is prebuffered for pattern matching. (Dawid Weiss) * SOLR-3068: Fixed NPE in ThreadDumpHandler (siren) * SOLR-2912: Fixed File descriptor leak in ShowFileRequestHandler (Michael Ryan, shalin) * SOLR-2819: Improved speed of parsing hex entities in HTMLStripCharFilter (Bernhard Berger, hossman) * SOLR-2509: StringIndexOutOfBoundsException in the spellchecker collate when the term contains a hyphen. (Thomas Gambier caught the bug, Steffen Godskesen did the patch, via Erick Erickson) * SOLR-2955: Fixed IllegalStateException when querying with group.sort=score desc in sharded environment. (Steffen Elberg Godskesen, Martijn van Groningen) * SOLR-2956: Fixed inconsistencies in the flags (and flag key) reported by the LukeRequestHandler (hossman) * SOLR-1730: Made it clearer when a core failed to load as well as better logging when the QueryElevationComponent fails to properly initialize (gsingers) * SOLR-1520: QueryElevationComponent now supports non-string ids (gsingers) * SOLR-3024: Fixed JSONTestUtil.matchObj, in previous releases it was not respecting the 'delta' arg (David Smiley via hossman) * SOLR-2542: Fixed DIH Context variables which were broken for all scopes other then SCOPE_ENTITY (Linbin Chen & Frank Wesemann via hossman) * SOLR-3042: Fixed Maven Jetty plugin configuration. (David Smiley via Steve Rowe) * SOLR-2970: CSV ResponseWriter returns fields defined as stored=false in schema (janhoy) * LUCENE-3690, LUCENE-2208, SOLR-882, SOLR-42: Re-implemented HTMLStripCharFilter as a JFlex-generated scanner and moved it to lucene/contrib/analyzers/common/. See below for a list of bug fixes and other changes. To get the same behavior as HTMLStripCharFilter in Solr version 3.5 and earlier (including the bugs), use LegacyHTMLStripCharFilter, which is the previous implementation. Behavior changes from the previous version: - Known offset bugs are fixed. - The "Mark invalid" exceptions reported in SOLR-1283 are no longer triggered (the bug is still present in LegacyHTMLStripCharFilter). - The character entity "'" is now always properly decoded. - More cases of
