I get that part of the point of this cost estimate is to avoid the (potentially-expensive) rewrite if, e.g. we can do a doc-value rewrite instead, but I'm thinking we could do something a little bit more term-aware. How expensive is `MultiTermQuery#getTermsEnum()`? I think it's cheap, but I'm not positive. Maybe we could get it, try walking through it, summing doc freqs, giving up if the number of terms gets big. We could go down that path only if the cost estimate from the existing logic is very high. I can try sketching out a PR with a test for it. -- This is an automated message from the Apache Git Service.
