I thought I was able to turn of the ability for non-friends to search me but apparently not. I'd prefer that only friends can view my profile (and if I wanted new ones I would add them). This doesn't seem possible. Is there a way to turn off the add friend button on my account? Also how do you limit the content such as timeline and photos non-friends can view? I used another Facebook account that isn't a friend of my own and I could see lots of my personal information. 
How to improve privacy from non-friends on Facebook?
