> The UnifiedHighlighter (and original Highlighter) highlight phrases by
> converting to a SpanQuery and using the Spans start and end positions to
> assume that every occurrence of the underlying terms between those positions
> are to be highlighted. But this is inaccurate; see LUCENE-5455 for a good
> example, and also LUCENE-2287. The solution is to use the SpanCollector API
> which was introduced after the phrase matching aspects of those highlighters
> were developed.
