New Game not showing up in Search

How long does it take for a game to appear in the Game Finder or in the list of Joinable Games after it has been created? So far it's been three hours, and it's still not showing up.
Sorry, let me clarify:
A friend of mine set up a game, and I can't join because it's not showing up in the searches.
