The KB list search matched only shortdescription + keywords, so searching a topic (e.g. "Spotfire", the Application name) surfaced just the one article whose title/keywords contained the word, not the others tied to it by topic. Match the topic too via an appid IN (apps named like the term) subquery - used instead of a join so it does not collide with the sort=topic join, and articles with no app still match on title/keywords.
