Class ExtendedQueryParser

java.lang.Object
  org.apache.lucene.queryParser.QueryParser
      org.apache.lucene.queryParser.ExtendedQueryParser

All Implemented Interfaces:

org.apache.lucene.queryParser.QueryParserConstants

public class ExtendedQueryParser
extends org.apache.lucene.queryParser.QueryParser

An extended version of the original Lucene QueryParser with the following set of additions:

• Allows the host application to reuse the field query creation algorithm and specify an analyzer when overriding getFieldQuery(String, String, boolean).

Since:

v3.3.0-atlassian-2

                                                throws org.apache.lucene.queryParser.ParseException

Creates a new field query using the specified analyzer instance for reuse in sub-classes.

Contains the same logic specified in the getFieldQuery method of the LuceneQueryParser parent class with an additional analyzer parameter so we can specify a different analyzer.

Backported to Lucene 3.3.0, as per the fix to LUCENE-2892.

IMPORTANT:

• Please update this algorithm to match the behaviour of super.getFieldQuery(String field, String queryText, boolean quoted) when updating the lucene version targeted by this library.
• This is part of lucene core since 4.0-ALPHA, so it is only needed for versions before that.

Throws:

org.apache.lucene.queryParser.ParseException
