How to find a person on Facebook?

[Valsorym]

I recently was on a vacation in Italy and I met a girl I wanted to chat with, however I didn't have any chance for getting to her and at least asking her to add me on Facebook. So I'm back home now, but I still want to add her. I don't know her name or where exactly she lives, but I'm completely sure that i would recognize her face and i also know that she speaks German as her main language (so she must come from Germany/ Austria/ Switzerland). Already tried to use the Facebook Graph API with a number generator (to go through all the profiles and filter them), but there is a rate limit (which makes it impossible). I also created a new account to try out the Open Graph Search, but that one is painfully slow and must be browsed manually. I also tried searching for people who checked in while at the hotel or ticked their location there (photos etc), but she probably didn't do that.
Any ideas? And yes, I am willing to invest a ton of computing power, time and bandwidth JUST TO FIND HER.

So the things I know: age category (inaccuracy about 5 years maximum), language (->country), gender (sex), face (I remember it, but I have no photos)

Please help!
"?": I don't know the name! o.O

Aww....
Theres the search at the top and you can type in first names and search through the lot for a while, do try searching in her country's face book. I most often even though I know their name scan down the side till I recognise a persons avatar.
Good Luck I hope you find her....she's very lucky!
Click my name and could you see if you can answer mine?

Its very very hard to find if you don't have name or id. I suggest you if you know her friends or someone or may be know the hotel she stayed go and get her name then only you can find. Best of luck
