Has anyone implemented some social/collaboration features on top of SOLR? What I am thinking is ability to add ratings and comments to documents in SOLR and then be able to fetch comments and ratings for each document in results (and have as part of response from SOLR), similar in fashion to MLT results. I think a separate index or separate core to store collaboration info would be needed, as well as a search component for fetching collaboration info for results. I would think this would be a great feature and wondering if anyone has done something similar.
