How to search/find someone in facebook who has a privacy option set so you cant normally search for them?

[Ken Adams]

I have a friend who has a Facebook account, I wish to add them as one of my friends but they have a privacy option set so that you cant actually find them when you search there name in facebook. They cant seem to disable the option so I wanted to know if there is any other way to search for someone who is a member but not through actual facebook because they have high privacy settings.

Any help would be appreciated.

You can get the privacy option fromt he settings. Yes you can make your own profile as invisible.
