If I could get at the number of tokens in a query or query norms I
might be able to use that in conjunction with field norms to measure
how close the query is to the field in terms of number of tokens. Then
regular mm could do the trick.

Hmm... Not necessarily. I'd be happy with any ordering for now. Though
some notion of order and slop would be nice in the future

Does order matter? By "exact" you mean the same tokens in the same positions?
