> 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
