Core Spotlight is a framework in iOS development that allows developers to index and search content within their app. It provides a way to make the app's content searchable and discoverable by the user through the iOS Spotlight search.
The concept of Core Spotlight revolves around two main components: indexing and searching.
Indexing involves creating searchable items, which are instances of CSSearchableItem. These items represent the content that the app wants to make searchable. Each searchable item contains a unique identifier, a domain identifier, and a set of attributes that describe the item's content. These attributes can include text, images, URLs, and more. The app can create and update searchable items as needed, ensuring that the index stays up to date with the app's content.
Searching is the process of querying the index for specific content. The CSSearchQuery class is used to perform searches. Developers can specify search criteria, such as keywords or attribute values, to retrieve relevant search results. The search results are returned as instances of CSSearchableItem, which can then be used to display the search results within the app.
Core Spotlight also provides support for user activity indexing, which allows developers to index user activities within their app. This means that specific user actions, such as viewing a document or performing a specific task, can be indexed and made searchable. This feature enhances the user experience by allowing them to quickly access their previous activities directly from the iOS Spotlight search.
In summary, Core Spotlight is a powerful framework in iOS development that enables developers to make their app's content searchable and discoverable through the iOS Spotlight search. It provides indexing and searching capabilities, allowing users to easily find and access specific content within the app.
