Robert Muir updated LUCENE-4648: -------------------------------- Attachment: LUCENE-4648.patch > PostingsHighlighter should score only with within-document statistics > --------------------------------------------------------------------- > > Key: LUCENE-4648 > URL: https://issues.apache.org/jira/browse/LUCENE-4648 > Project: Lucene - Core > Issue Type: Improvement > Components: modules/other > Affects Versions: 4.1 > Reporter: Robert Muir > Attachments: LUCENE-4648.patch > > > PostingsHighlighter (in sandbox) treats documents to be highlighted as > collections of small documents (snippets). > But (like the other highlighters), it uses collection-wide stats to score the > snippets. It actually calls the indexsearcher method which might even result > in a distributed call. I don't think its worth it to do all this. It means we > have to reseek to all terms across all segments at the minimum, and it means > snippets change over time and so on. > I think its good enough to only use within-document stats. And it might speed > up highlighting. -- This message is automatically generated by JIRA.
