Have you tried using PrecedenceQueryParser instead of the standard one? http://lucene.apache.org/java/3_3_0/api/all/org/apache/lucene/queryParser/precedence/PrecedenceQueryParser.html It probably does the right thing. (Related but not part of the answer: I solved the issue here by making it a parser-level feature, since I was making my own parser anyway. When we get the AST from the parser, the precedence has already been figured out.)
