I responded on dev: http://www.lucidimagination.com/search/document/1a050d81afda938/best_way_to_gather_span_token_positions_from_query
because I thought it was a fair dev question. I'd really love to
see both span query support and payload support in Solr.

Hello,
I'm trying to find a decent approach for getting token positions out
of (or is that into?) Solr query results. Is the best approach to
extend
a QueryComponent and/or HighlightComponent? I'm new to solr, and still
on fairly shaky ground so any pointers or suggestions are quite
welcome.
As a little BACKGROUND:
I am trying to migrate a custom lucene-only content anaylsis
project to solr. The 'old' system programmatically runs a few thousand
predefined queries against a corpus, and then analyzes the results.
The
lucene score is good, but the actual position of the hits is also
quite
important.
My previous system did a simple query parsing to create SpanQuerys,
and then used a modified dumpSpans() to get the token position from
the
spans. Now I am trying to find how to use solr's goodness (and
MemoryIndex approach?) to get the span positions in a more logical
manner. I think the answer is in the highlighter, but I'm getting a
little twisted around, and could use a pointer.
I am using a recent Solr nightly snapshot, grails, Aduna Aperture,
and Intellij (if any of that matters). Also, I posted this to the dev
list, incorrectly I believe; apologies for the cross posting.
Thanks,
Sean
