-----------------------------------
Summary: 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
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.
