Hi!
Jane, now we are really going into the field of elastic search's relevancy calculation. When searching, things like popularity (pageviews), incoming links, number of different language wiki articles, article size, article quality (good/selected), and many other aspects could be used to better the results. I wish these were available together with the WDQS results, possibly as a number similar to Google's "page rank".
See https://phabricator.wikimedia.org/T141813. It is on the TODO list, but I'm not sure if I get to it this Q (maybe, maybe not). If we make it talk to Elastic, I imagine anything available to Elastic would be possible to use, but no promises since I didn't research it yet.
