Subject [GitHub] lucene-solr issue #105: LUCENE-7526 Improvements to UnifiedHighlighter Offse...

    https://github.com/apache/lucene-solr/pull/105
  
    I don't think there's a way to avoid keeping the position state, unfortunately.  The reason
is that we can move one of the postings enums to the next position, but then realize the next
position for that term is behind the position for a different term (and postings enum) that
also matches the wildcard.  Then we'll update the top and switch to the next postings enum
(by offset now), but once it's exhausted or we switch back to the previous one from interleaving
the position is lost.  :/  An alternative to avoid this would be to change PostingsEnum to
allow fetching of the currentPosition, then nearly all the house keeping would go away.
