Does anybody have a solution to create, let's call them,
Google like extents with highlighted (embolded) result words?

One option, of course, is to load each file from result list and search out
necessary extents...

I'm wondering - is there possibility to "reverse engineer" textual data from
Swish index (maybe concatenating words by positions from index file around
result words or so) and that way create some extents from result file.

Hope you got my idea

Thanks
