> 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
