Description

FastVectorHighlighter will not highlight on MultiPhraseQuery - will instead just skip and return results.

Example:
I have synonyms.txt file and it contains
break,breaks,broke,brake

If I search for "brake vehicle", the query parses to MultiPhraseQuery with brake vehicle, break vehicle, breaks vehicle, broke vehicle as possible matches. Would like highlighting to occur on all of those results. Currently there are no highlighting results at all.

Research direction

Start by locating FastVectorHighlighter handling for MultiPhraseQuery and reproduce the example using synonyms.txt with the query "brake vehicle". Done means highlighting is returned for results matching brake, break, breaks, or broke followed by vehicle, rather than being skipped.
