It seems to be broken. I searched for "ale" and your entry came up. I searched for "quest" (my thread) and no results.Have just done a few searches and had no results, so began working done to searches that I would have expected to yield results "Beer" 1 result, "Ale" 0 results.
I logged out/in on two different devices, phone and desktop PC, three different browsers on PC: Chrome, Edge and Firefox. All with the same result. Only worked for certain words not others.I tried searching the word Beer again a moment ago and got hundreds of results, i did log out last night as i have been having browser problems maybe worth a try if you find search still broken.
