Hi Chris,
I misunderstood your requirement. I am not aware of some facet result filtering feature. What you could do is sort facet results by sum and load page by page but that does not sound like a good solution. Did you try using streaming expressions - I don’t have much experience with this feature so would have to play a bit before giving answer if possible and how to do it, but I guess someone will be able to give some pointers.
