This document discusses how to make app content searchable using Core Spotlight and NSUserActivity on iOS. It provides steps to index app content using Core Spotlight, which is best for relatively static data. It also discusses using NSUserActivity to index user activities and dynamic content the user has interacted with. Both Core Spotlight and NSUserActivity use NSUserActivity and return search results in the userInfo dictionary, which can then be used to present relevant content to the user.
