How do I work Facebook?

[mkt]

2 Facebook questions: People search isn't working for me & how does "Restriction" work?

1.) If I search a person, I put in say John Doe & several names show. So I hit "people" on the right side of the screen & then it says "No results found for your query". But...I just SAW all the John Does! So they're in there but I can't search them?

2.) I have an old friend who wants to be a Facebook Friend. I really don't want this person to see EVERYTHING. So, can i restrict them - yet allow certain things on a case by case scenario? Like, THIS picture is ok, but not that one...THIS comment is ok, but not THAT one. Know what I mean?
