bq. I hope this helps to keep the PQP

Why? If the new queryparser properly supports precedence (which I've
been told it can/does in the past), whats the attachment to PQP? Even
testPrecedence fails :) I havn't looked into it, just doesn't seem
promising :)


 * Experimental query parser variant designed to handle operator precedence
 * in a more sensible fashion than QueryParser.  There are still some
 * open issues with this parser. The following tests are currently failing
 * in TestPrecedenceQueryParser and are disabled to make this test pass:
 * <ul>
 * <li> testSimple
 * <li> testWildcard
 * <li> testPrecedence
