Thanks Steven, that's just the kind of feedback I needed. And thanks also to Jan. I'll do a little clean-up on my filter and submit it...

Maybe it could be called StopTermTypesFilter? (Plural on Types to signify that more than one type of term can be stopped by a single instance of the filter.) Such a filter should have an enablePositionIncrements option like StopFilter.
