I\'ve got an unusual situation. Normally when you search a text index you are searching for a small number of keywords against documents with a larger number of terms.
only setting mm parameter will not satisfy your needs since
"the quick brown fox jumps over the lazy dog"
will match all three documents
and as you said:
I'd like to find the documents that have a phrase that occurs in the query. In this case "quick brown" and "lazy dog" (but not "fox over" because although the tokens match it's not a phrase in the search string).
