Subject [jira] [Updated] (LUCENE-4860) PostingsHighlighter should pass field name to PassageFormatter.format?
Date Wed, 20 Mar 2013 17:29:20 GMT


Michael McCandless updated LUCENE-4860:

    Attachment: LUCENE-4860.patch

Here's one possible approach ... it just add .getFormatter/.getScorer each taking String field,
so subclass can pick an impl up front depending on the field name.

> If the app needs to render different fields (eg multi-valued vs single-valued) differently
it's tricky now.
> You can do Passage[0].getMatchTerms()[0].field(), but then that doesn't work if that
field hit the empty highlight.
> I think we should pass the fieldName to format directly?  And then maybe change getMatchTerms()
to return BytesRef[] instead (the field name is redundant: they are all the same for all passages
passed to format).
