Subject [jira] [Commented] (LUCENE-7575) UnifiedHighlighter: add requireFieldMatch=false support
Date Mon, 05 Dec 2016 22:35:58 GMT


Ferenczi Jim commented on LUCENE-7575:

I was thinking a bit more about the wastefulness of re-creating SpanQueries with different
field that are otherwise identical. Some day we could refactor out from WSTE a Query ->
SpanQuery conversion utility that furthermore allows you to re-target the field. With that
in place, we could avoid the waste for PhraseQuery and MultiPhraseQuery – the most typical
position-sensitive queries.

I agree, I'll work on this shortly. Thanks for the hint ;)

> The UnifiedHighlighter (like the PostingsHighlighter) only supports highlighting queries
for the same fields that are being highlighted.  The original Highlighter and FVH support
loosening this, AKA requireFieldMatch=false.
