Get TermVectors for query hits only
Hi all,
When I'm using the TermVectorComponent I receive term vectors with all
tokens in the documents that meet my search criteria. I would be
interested in getting the offsets for just those terms in the documents
that meet the search citeria. My documents are about 200 K and are in
XML. If I have just the offsets for the hits, I can easily implement my
own highligting on the client side.
Does anyone know how to go about doing this?

Thanks Grant,
I think I get the idea.

I seem to recall that the Highlighter in Solr is pluggable, so you may
want to work at that level instead of the client side. Otherwise, you
likely would have to implement your own TermVectorMapper and add that
to the TermVectorComponent capability which then feeds your client.
For an example of using TermVectorMapper, but not solving exactly your
problem (but close), see http://www.lucidimagination.com/blog/2009/05/26/accessing-words-around-a-positional-match-in-lucene/
but note that is at the Lucene level.
