Class PrecedenceQueryParser

java.lang.Object
  extended by org.apache.lucene.queryParser.core.QueryParserHelper
      extended by org.apache.lucene.queryParser.standard.StandardQueryParser
          extended by org.apache.lucene.queryParser.precedence.PrecedenceQueryParser

public class PrecedenceQueryParser
extends StandardQueryParser

This query parser works exactly as the standard query parser ( StandardQueryParser ), except that it respect the boolean precedence, so <a AND b OR c AND d> is parsed to <(+a +b) (+c +d)> instead of <+a +b +c +d>.

EXPERT: This class extends StandardQueryParser, but uses PrecedenceQueryNodeProcessorPipeline instead of StandardQueryNodeProcessorPipeline to process the query tree.
