Class CompassQueryParser

java.lang.Object
  org.apache.lucene.queryParser.QueryParser
      org.compass.core.lucene.engine.queryparser.CompassQueryParser

All Implemented Interfaces:

QueryParserConstants

public class CompassQueryParser
extends QueryParser

Extends Lucene QueryParser and overrides getRangeQuery(String,String,String,boolean) since lucene performs data parsing which is a performance killer. Anyhow, handling dates in Compass is different and simpler than Lucene.
