: Sorry, like the subject, I mean the total number of terms. it's not stored anywhere, so the only way to fetch it is to actually iteate all of the terms and count them (that's why LukeRequestHandler is slow slow to compute this particular value)
If i remember right, someone mentioned at one point that flex would let you store data about stuff like this in your index as part of the segment writing, but frankly i'm still not sure how that iwll help -- because you unless your index is fully optimized, you still have to iterate the terms in each segment to 'de-dup' them. -Hoss
