disabling facebook public search feature?

[BeBe]

I don't want my facebook page showing up if people google me. So I went to privacy settings and unchecked "enable public search" but my facebook is still showing up when I enter my name into google? why is this? does it take awhile to work? also, will this prevent my page from ever showing up if a facebook friend's name is entered into google. (basically I don't want my facebook showing up in a google search no matter what someone enters into the search engine)
