Kerry, What an interesting idea. I created a task in Phabricator, Wikimedia's took for tracking bug and feature requests. I'll bug some of the search folks to see if they have any suggestions. In the task I shared a very clunky way of doing this that is not 100% what you're looking for, but something! :)
