how do i do an advanced search for someone on facebook?

[Molly]

i dont have facebook and my cell phone broke so i am trying to get a hold of my sister. she has a common name and facebook is so different (made a random account) that i cannot figure out how to do an advanced search for her email/ location/ school. help please?
i live in a different city than my family, i moved away for college but my sister and i grew up together. i have their emails but they don't check them.

when i used to have facebook, it had a function to advance your search to people with that name from a certain school or something. it helped because a lot of people have the same name. how are you supposed to find anyone??
