I don't think you understand me. Say I only have one document indexed and it's contents are "Foo Bar". I want this documented returned if and only if the query has the words "Foo" and "Bar" in it. If I use a mm of 100% for "Foo Bar Bazz" this document will not be returned because the full user query didn't match. I i use a 0% mm and search "Foo Baz" the documented will be returned even though it shouldn't.
