This is a ton of discussion on this if you search the lucene user list
(QueryParser and precendence and the 'binary' operators). I have seen
many mentions of the precedence parser still having open issues but no
mention of what those issues are.

OK, I see that I'm not the first to discover this behavior of
QueryParser.
Can anyone vouch for the integrity of the PrecedenceQueryParser here:
http://svn.apache.org/repos/asf/lucene/java/trunk/contrib/miscellaneous/src/java/org/apache/lucene/queryParser/precedence/
Thanks,

Correction:
The query parser produces the correct query with the parenthesis.
But, I'm still looking for a fix for this. I could use some advice on
where to look in QueryParser to fix this.
Thanks,
