The text being displayed "stream_source_info ..." is the literal value coming from the "fulltext" or "fulltext_hl" field value in your Solr "search" core. I'm not sure why the literal value is being shown instead of just the parts of fulltext containing the search terms, but this should give you an idea where to start looking.
