 * 
 * During ResponseBuilder.STAGE_PARSE_QUERY we parse, optimize, compile and
 * execute the XQuery query. When a lux:search call is encountered, it will
 * create a SearchResultIterator, which creates a Lucene Query and calls
 * back into the SearchHandler; then subsequent phases are handled by the
 * normal QueryComponent.
