David Smiley commented on LUCENE-7863:
--------------------------------------
bq. I suppose if it repeats postings, it also repeats positions, offsets,
payloads. Doesn't it?
Nope! Configure it for IndexOptions.DOCS only -- no rest of that stuff. Then
you could write a TermsEnum wrapper that delegates to the original field that
has all the rest of that stuff. For inspiration, see
TermVectorFilteredTermsEnum in the unified highlighter. It's not the same but
the idea is that you blend 2 TermsEnum.
> Don't repeat postings and positions on ReverseWF, EdgeNGram, etc
