Class RegexQuery

java.lang.Object

org.apache.lucene.search.Query

org.apache.lucene.search.MultiTermQuery

org.apache.lucene.sandbox.queries.regex.RegexQuery

All Implemented Interfaces:

Cloneable, RegexQueryCapable

Deprecated.

Use core's regex query.

@Deprecated
public class RegexQuery
extends MultiTermQuery
implements RegexQueryCapable

Implements the regular expression term search query. The expressions supported depend on the regular expression implementation used by way of the RegexCapabilities interface.

NOTE: You may wish to consider using the regex query support in RegexpQuery instead, as it has better performance.
