Looking at what you wrote:
I am doing a weighting system where I rank documents that have Term 1 AND
Term 2 AND Term 3 more highly than documents that have just Term 1 AND Term
2, and more highly than documents that just have Term 1 OR Term 2 but not
both.
Couldn't you maybe get the same effect using some clever term boosting?
I.. think something like
"Term 1" OR "Term 2" OR "Term 3" ^ .25
would return in almost the exact order that you are asking for here,
with the only real difference being that you would have some matches for
only Term 3 way way at the bottom of your list score wise.
It might be worth investigating something like this, where you cut off
displaying documents that don't match a certain score thresh hold. Thus
cutting out the matches that you don't want (The term3 only ones)
