I was thinking of putting together a simple "highlighter" that just returns
if a field contains a match or not. This sounds like a nice logic
extension to that. It probably wouldn't actually be a "highlighter" but I
imagine it'd run during the highlight phase and function similarly. It'd
need something like the highlight_query, for example, to function
properly. Anyway, I believe the short answer is, if you are looking for
something specific, file an issue on github.
