You could write your own request handler, but I think the route that  
most people take is to stop using lucene query syntax and move to  
dismax params to express requirements.  This also plays better with  

NOT clauses -> fqs

required clauses (either OR or AND) -> q + mm

purely optional clauses -> bq/bf

If you want complicated (read: parenthesized) boolean logic, it's  
best to develop your own solution.
