Is Everyone On Facebook Searchable Now?

[TP]

Has facebook yet fully disabled their "make unsearchable" feature?

Met this girl at a party, got her first name, knows what city she's from, knows the college she's currently attending, but I for the life of me couldn't find her on facebook, having search her through all sorts of filters. We have no common friends. Seeing her personality and her huge social life, I have a hard time imagining her not having a facebook account.

I've also recently reconnected with two girls from my high school, which I have viewed their profiles before a year ago, which I didn't added them. But not, trying to search for them again, knowing their full names, and where they live, I couldn't search them either. Highly doubt they would delete their accounts as well.
