> ANDScorer, NOTScorer, and RequiredOptionalScorer all subclass PolyMatcher,
> like ORMatcher/ORScorer.  
> These three matchers are much simpler to implement than ORMatcher/ORScorer:
> ORMatcher.c is longer than the other three .c files combined.  OR-combining is
> simply much harder to do well when proceeding doc-at-a-time, and the optimized
> code in ORMatcher.c takes up more space.
