David Smiley commented on LUCENE-7863:
--------------------------------------
oh right I was thinking of freq, positions, offsets, payloads. It's true my
suggestion repeats the postings (doc ID list) but at least not the rest. I
don't see how auxiliary docs would help. Maybe something is possibly by
wrapping another codec.
> Don't repeat postings and positions on ReverseWF, EdgeNGram, etc
