[KinoSearch] Feature request: highlight without excerpt

[Edward Betts]

I'd like to be able to highlight the matches in a field without
creating an excerpt from it. A typical use case would be for
highlighting in titles, like Google does.

I would have a go at implementing it, but I'm not sure how best to fit
it into the class hierarchy, and where to put the result in the data
structure returned by fetch_hit_hashref.

Thanks
