Well, now I'm thinking what I saw was a search burp because some later searches over at Elemental showed a bunch of clutter from off-topic threads.
Is there any chance we'll ever be able to search just the topics we want to read (an 'Advanced' local search)? Ever since the cross-site merger thingy got so big, it has been much harder to use the site: search limiter to help searches because the domain names don't mean quite what they used to.
Unfortunately not, based on the tools available to me from Google. However, I have started discussions with our database guy in possibly bringing back direct database search, so that we don't have to go through Google. But don't expect it anytime soon, this is probably months off as it requires new servers to handle the load, some code updates, and likely other changes.
Superbly effective workaround process of the Search Function - finally ours to use again!
I can only guess, busy devs have gained some well deserved slack from a thoroughly ready & solid beta compiled version of Elemental.
I wish
