[jira] Resolved: (LUCENE-792) PrecedenceQueryParser misinterprets queries starting with NOT

["Robert Muir (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-792?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Robert Muir resolved LUCENE-792.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 4.0
                   3.1

The precedence queryparser is now fixed for this bug, its implemented with the QP in contrib per LUCENE-1938

I verified with this test case (which I committed):
{noformat}
  // LUCENE-792
  public void testNOT() throws Exception {
    Analyzer a = new MockAnalyzer(MockTokenizer.WHITESPACE, false);
    assertQueryEquals("NOT foo AND bar", a, "-foo +bar");
  }
{noformat}

> "NOT foo AND baz" is parsed as "-(+foo +baz)" instead of "-foo +bar".
> (I'm setting parser.setDefaultOperator(PrecedenceQueryParser.AND_OPERATOR) but the issue applies otherwise too.)
