This sounds interesting. I take it the existing numeric fields can't already do stuff like this? (We don't have access to them yet anyway for backwards compatibility reasons, otherwise I would have looked into it. But next major version...) For now I am writing a routine which subdivides the term space until it thinks it's down to some size which is small enough to use iteration instead of seeking (which seems to be in the realm of 100,000 ~ 1,000,000 terms -- but the hard thing is guessing how many terms would be either side of the split.)
