If you just start typing a person name in the Facebook search box(displayed in blue upper bar on your profile) then suddenly within a fraction of a second search results appear and they comes much more faster if that person already exist in your profile.

so i just want to know that what is behind this search.i mean to say that which software tool and algorithm they are using for it.

i know that no one other than Facebook can explain exactly about it thats why i am just asking to give me an idea about that.

i am sure that they are using something which is open source.

what's your interest
