iPhone: what is the search-list view controller called?

I'm just beginning iPhone development, so please bear with me.

I'm looking to make the first view of my application look like the search tab in the App Store, with a search box at the top and a list of results, and while the user is typing hopefully show the last-searched-for items.

Please point me in a good starting direction; is that a specific controller that I can just utilize, and if so, which one? Or where would I开发者_运维知识库 begin in creating it?

This is called the UISearchDisplayController. Really easy to implement.
