The wiki page (http://wiki.apache.org/solr/MoreLikeThis) says:
mlt.fl: The fields to use for similarity. NOTE: if possible, these should have a stored TermVector I didn't set TermVector to true MoreLikeThis with StandardRequestHandler seems to work fine. The first question is, is TermVector only for performance optimization? The second question is, afterI changed the mlt.fl fields from both indexed and stored to indexed only, I started to get zero results back. Do mlt.fl fields always need to be stored? Thanks
