Chrome's app launcher has an interesting way to match results. Let's say you want to open Google Play Music. You can search for google play music, play music or you can just type the the first letter from each word and search for gpm. It also works if you type the first letters from the first word, followed by the first letters from the second word and so on. For example, you can also search for goplm, gplam, gmu.
Another example: launch Mahjong Solitaire by searching for ms.
