If I delete a Facebook group; how long does it take for it to disappear from search engines?

I recently deleted a facebook group at the request of someone. It was not a malicious group but they requested that I take it down. I did. However, it still shows up on Yahoo search. Do these inactive groups just disappear after a while or is there a process I need to go through to get them deactivated?

Usually it takes about 2 weeks (14 weeks) I know its a long process , but it might even come down before that (: and , no you don't have to go through and deactivate it .
