For what it's worth, I had the same question last year, and I never really got a good solution: http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201212.mbox/%3C81 e9a7879c550b42a767f0b86b2b81591a15b...@ex4.corp.w3data.com%3E
I dug into the highlight component for a while, but it turned out I couldn't use that approach. I'm afraid I don't recall exactly why. The debugQuery method had a *huge* performance cost, so that was a non-starter. I managed to solve a subset of my problem by writing a custom QueryComponent that (re)examines the documents being returned and annotates the response. This worked because I was able to reduced my problem space to just determining whether a document was a string-literal match with the query vs via synonyms or other fuzzy expansion. It still required that I had stored and was returning the fields I wanted to (re)examine, so it was hardly ideal on several fronts. If you can, I'd suggest just doing two queries.
