> If a proximity phrase query overlaps with any other query term it will not be highlighted.
> Example Text:  A B C D E F G
> Example Queries: 
> "B E"~10 D
> (D will be highlighted instead of "B C D E")
> "B E"~10 "C F"~10
> (nothing will be highlighted)
> This can be traced to the FieldPhraseList constructor's inner while loop. From the first
example query, the first TermInfo popped off the stack will be "B". The second TermInfo will
be "D" which will not be found in the submap for "B E"~10 and will trigger a failed match.
