How does Facebook determine the order of the results when you type in a letter into the Facebook search bar?
When you type in a letter into the Facebook search bar, it pre-lists a bunch of results of your friends. The order of your friends’ names aren’t in alphabetical order. I’m not sure if its if you view their page more or maybe they view your page more, it moves them up. But I haven’t been able to prove it, so I doubt that theory.
