Chris, Yes, when there are multiple types of queries involved (Term & Wildcard in this case) that's how I handle it. A disadvantage of this is that the user input must be somewhat restricted since you need to know what's coming.
An important thing to remember is that Wildcard, Prefix and one other I can't remember at the moment (sorry :>() are not passed through an analyzer. So, the QueryParser's analyzer has no effect on them.

So you created your own BooleanQuery and parsed the string yourself, adding strings as TermQuerys etc., rather than using a QueryParser ?
