Unintended feature of Deep Research – esoteric search

I searched for a video I once saw and couldn't find it, not with google not with grok search or gemini search or chat-gpt search. It was frustrating. I know Deep Research wasn't intended for this but I gave it the task of finding this half remembered video about a chess game. It found it! I was Impressed. Since then I used it again to find vaguely remembered things that are impossible to google. It succeeded 3 out of 3. Very cool
