Subject Re: MoreLikeThis match

Actually, what is the difference between "match" and "response"? It seems
that match always returns one result but I've thrown a few cases at it where
the score of the highest response is higher than the score of match. And
then there are cases where the match score dwarfs the highest response
score.
