Constructor and Description
QueryTerm(boolean casesensitive, java.lang.String searchmode, java.lang.String value) Construct a new instance of a query term for a free text search (using the value only)
QueryTerm(boolean casesensitive, java.lang.String searchmode, java.lang.String value, java.lang.String pathexpr) Construct a new instance of a query term for a structured search (matching the value only for those nodes in the pathexpr)

Method Summary

java.lang.String	getPathExpression() get the path expression parameter
int	getPercentageSymbolCount() get the percentage count for one query term
java.lang.String	getSearchMode() get the searchmode parameter

boolean	hasSameSearchValue(QueryTerm term) Compare two query terms to see if they have same search value.
boolean	isCaseSensitive() determine if the QueryTerm is case sensitive

QueryTerm

public QueryTerm(boolean casesensitive,
                 java.lang.String searchmode,
                 java.lang.String value)

Construct a new instance of a query term for a free text search (using the value only)

Parameters:

casesensitive - flag indicating whether case is used to match

searchmode - determines what kind of substring match is performed (one of starts-with|ends-with|contains|matches-exactly)

value - the text value to match

QueryTerm

public QueryTerm(boolean casesensitive,
                 java.lang.String searchmode,
                 java.lang.String value,
                 java.lang.String pathexpr)

Construct a new instance of a query term for a structured search (matching the value only for those nodes in the pathexpr)

Parameters:

casesensitive - flag indicating whether case is used to match

searchmode - determines what kind of substring match is performed (one of starts-with|ends-with|contains|matches-exactly)

value - the text value to match

pathexpr - the hierarchical path to the nodes to be searched
