For all that its name sounds like an asteroid base -- or a software company's internal codename -- Wolfram|Alpha is the darnedest unsearch engine ("Computational Knowledge Engine") I've seen. It'll solve differential equations (and show its work) and can give a good answer to "How hot is it?" Bing and Siri are both said to ring it up when they get in over their heads. --And it has its own gift shop.
You're on your own about the T-shirts, coffee mugs and hoodies but you might like to try the Thing Itself, next time the Usual Search Suspects are struggling to make sense of whatever it was you were looking for.
(Title refers, somewhat obliquely, to A Logic Named Joe, the first science fiction story about The Internet, by the underrated but brilliant Murray Leinster. It would only confuse you to add that he wrote it in 1946.)
