Google has added the ability to search through your Photos library using emoji. The emoji search works pretty much like text search. The search engine tries its best to match photos with the entered emoji. As you can see in the image above, searching for a tiger emoji pulled up the one picture of a tiger I had in my library. The search should work best for animals, vehicles, or food emoji, but for anything else you'd have to bust the standard keyboard. While it did seem like an April Fools' prank at first, it does work, and you can try it out for yourself. Source
