> 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
> See https://builds.apache.org/job/Solr-reference-guide-master/javadoc/highlighting.html
