Document QueryParser's boolean precedence ignorance [LUCENE-3675]

[asfimport]

Please add to the JavaDocs that the QueryParser does not handle boolean preference with AND/OR. This confuses developers in the way the understand boolean terms with AND. As mentioned by Uwe Schindler. This issue is connected with #4748.

Where is the difference to the previous issue? It's both about documenting the same thing and pointing user to PrecedenceQueryParser.
