Xapian::Query::get_terms_begin() and
Xapian::Enquire::get_matching_terms_begin() help a lot here.

You actually want to rerun the indexing time parsing on the text to be
highlighted, rather than the QueryParser parsing.  Omega contains much
of the code required, though it doesn't highlight phrase matches as
phrases currently.

I was hoping to move this code to the core library for 1.0, though I'm
not sure I'd want to delay 1.0 if this is the only thing left to do.

As always, you're welcome to file "wishlist" bugs in the bug tracker.
