------------------------------------
Hey Mark H, any chance you will have some time to look at this soon?
Now that the test classes have been merged, any change to the current contrib
test class will break this patch.
I think everything is good except that we might want to alert which Highlighter
version caused the Junit test to fail., since almost every test is run with
both the standard and new Span Highlighter. I may just be nitpicking there
though.
> Extend contrib Highlighter to properly support PhraseQuery, SpanQuery,
> ConstantScoreRangeQuery

> 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, PhraseQuery, and ConstantScoreRangeQuery. New Query types are
> easy to add. 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.
