Not that I’m aware of. Snippet highlighting is something that was worked on for a GSoC project a few years ago, and is mentioned in our FAQ: <http://trac.xapian.org/wiki/FAQ/Snippets>. It’s not available in the 1.2 series, but as I understand it should work out of the box in 1.3.3.

Note that your suggested approach of going from terms to snippet doesn’t work in the general case, because of issues like stemming. Instead, Mihai’s approach was to use the matcher information to generate a snippet from the original, unstemmed and untermed, text.
