Alan Woodward commented on LUCENE-8249:
---------------------------------------
Here's an updated patch:
* minFreq() is now maxFreq()
* I fixed SloppyPhraseMatcher#maxFreq to be the sum of the freqs of each child
postings, on the grounds that each term position can be the first term in at
most one match. +1 on changing to a float, I'd missed that comment before
uploading the new patch, will change it now.
* ExactPhraseMatcher now advances its lead in sync with everything else, which
simplifies things a lot.
* I removed freq(), and replaced it with sloppyWeight() which returns the
contribution of the current match to the total sloppy freq - suggestions for a
better name are welcomed...
* I originally put in MatchesIterator#term so that highlighters could do things
like keep track of the number of specific terms in a fragment, for scoring. I
like the idea of changing it to return a BytesRef[] though, let's do that in a
followup.
