Subject [jira] Commented: (LUCENE-794) Extend contrib Highlighter to properly support PhraseQuery, SpanQuery, ConstantScoreRangeQuery
Date Tue, 29 Apr 2008 22:19:55 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593145#action_12593145

Brian Whitman commented on LUCENE-794:
--------------------------------------

I must be missing something, but after your commit, I did a clean checkout of lucene trunk,
did an ant dist and am getting the same MemoryIndex problem as I reported above. Before I
could just apply the patch after doing the ant dist first but now that the patch is in trunk
I can't get around that. How are you compiling lucene now from trunk?

> 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.
