Andy Liu commented on LUCENE-794:
---------------------------------
I gave this patch a whirl, and it looks great.
I do see one problem. Say a document contains:
x y z a b y z
and the query is:
"x y z"
the highlighter will return (with terms in brackets denoting highlighted terms):
[x] [y] [z] a b [y] [z]
Since the last y and z are not part of the full phrase, they should not be
highlighted.
> Extend contrib Highlighter to properly support phrase queries and span queries

> 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.
