How to integrate App Store pop up without leaving the current application

When you go to search in spotlight, the App store has its own section that allows you to bring up the App Store within that experience.


If I was to search Twitter (and not have Twitter installed, there would be app store suggestions, allowing me to view the application within the current exerpeine and eitehr (1) go back (2) down load the app seeing the app store page or (3) view in app store.


How does spotlight do this without using a broswer UI WebKit or moving the user out of their current experience and into the app store? Is this a new kit or feature that allows us to have a full page experience of the app store within another application/application experience?


Are the only three ways to integrate the app store into an app is (1) a URL broswer popup within the app exerience (2) the small grey half card asking for authenication for buying/downloading an app and (3) moving out of the app experience into the app store app itself.
