This is a nice little collection, definitely worth a read. My favorite is to tell Siri:
Show me pictures of my cats
Obviously, you’ll want to replace “my cats” with something that makes sense for you. This was a bit hit-or-miss for me, but I like the direction. Asking Siri to search for cats worked flawlessly for me. Other searches were way off or prompted Siri to turn to the web, which was not what I intended.
But this one also worked flawlessly:
Show me pictures of food
I had no idea I took so many pictures of stuff I like to eat. And now I’m hungry.
