-----------------------------------
Summary: Make UnifiedHighlighter the default in 8.0
Key: SOLR-12901
URL: https://issues.apache.org/jira/browse/SOLR-12901
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: David Smiley
Fix For: master (8.0)
I think the UnifiedHighlighter should be the default in 8.0. It's faster and
more accurate than alternatives.
The original highlighter however has some benefits:
* Different passage/snippet delineation options; somewhat more flexible.
Though no i18n BreakIterator based one.
* Seems to handle some "special" Queries and/or QueryParsers by default better
-- namely SurroundQParser. Though SOLR-12895 will address this UH issue.
* Considers boosts in the query when computing a passage score
* hl.alternateField, hl.maxAlternateFieldLength, hl.highlightAlternate options.
Instead the UH has hl.defaultSummary boolean
