Commit 101296f606f1fe60c3c804ca8bc5d541fad243d9 in solr's branch refs/heads/main from David Smiley
[ https://gitbox.apache.org/repos/asf?p=solr.git;h=101296f ]
SOLR-12901: make hl.method=unified the default (#579)
* fixed minor assertion failure about a RTimer state that could be wrong if the request is re-used
* did not switch ClusteringComponent; it will take more care, can happen later
* custom SolrHighlighter impls have to be chosen with hl.method=original
* Remove PostingsSolrHighlighter (deprecated), missed from SOLR-13138

> 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
