In the "apps on facebook"-documentation, in the "search" part following paragraph is outdated and should be updated:
"Each new app has its own App Profile Page (for example, see Facebook Live's page). This Page is similar to other Pages and user profiles on Facebook, and it includes Wall and Info tabs as well as other configurable tabs. When users search for your app, this Page shows up in the search type-ahead or on the search results page. From this Page, users can navigate to your app or Like the App Profile Page. You can also choose to update users who have liked your profile Page with news about your app."
