Parts of the QueryParser class are very old. I'm not sure exactly how much of it is old or hasn't even been ported, but I can say this probably has some effect on how the parser differs from the java version. I'm not sure about exact behavior differences, but this needs to be ported from scratch again to make sure that it's on par with Java's queryparser.
