Description

A project I'm working on requires term quorum searching with stemming turned off. The users are accostomed to Sphinx search, and thus expect a query like [ A AND (B C D)/2 ] to return only documents that contain A or at least two of B, C or D.

So this document would match:
a b c

But this one wouldn't:
a b

This can be a useful form of fuzzy searching, and I think we support it via the MM parameter, but we lack a user-facing operator for this. It would be great to add it.
