Mark, Thanks for responding and the tip about java-user.
So should I be able to do something like Queryparser.parse(q.ToString())? //Query q

For some queries its possible - the docs for Query say impls should
attempt to be parsable by the QueryParser - but in practice it's not
always the case. So you can't reallly count on it across the board.

By the way, these questions are best sent to java-user rather than general.
