Michael Goddard commented on LUCENE-794:
----------------------------------------
Mark,
I've still got a little work to do on it, but would like to also include
support for highlighting of RangeQuery within SpanNearQuery. I have a new
SpanQuery subclass which helps, and will post that to see if it merits
inclusion within Lucene. In conjunction with that, I'd have one last "else if"
clause to add to the patch covered by this issue. Basically, I'm trying to
make a case for the work covered in this Jira issue being committed, since it's
very useful to me.

> This patch adds a new Scorer class (SpanQueryScorer) to the Highlighter
> package that scores just like QueryScorer, but scores a 0 for Terms that did
> not cause the Query hit. This gives 'actual' hit highlighting for the range
> of SpanQuerys and PhraseQuery. There is also a new Fragmenter that attempts
> to fragment without breaking up Spans.
> See http://issues.apache.org/jira/browse/LUCENE-403 for some background.
> There is a dependency on MemoryIndex.
