To get the first n clauses you could maybe create your own query subclassing RegexQuery with an implementation of getEnum(reader) that returned a FilteredTermEnum that was a subclass of RegexTermEnum that stopped after the first n. That's made up from following the javadoc and I've no idea if it is practical or not. Perhaps someone else has a simpler suggestion.
