Marvin Humphrey commented on LUCENE-834:
----------------------------------------
Averaging is how I've got this implemented by default in KS. However, all
positions and boosts get read in at once. TermDocs/TermPositions has been
replaced by PostingList, which goes doc by doc. The type of Posting assigned
to each field (MatchPosting, ScorePosting, RichPosting, eventually
PayloadPosting) determines how much gets read in. (KS doesn't have any queries
that rewrite(), so it's only large docs that are an issue.)
I haven't yet worked out the mechanics of per-position boosts and phrase
queries.
