# init(queryString:attributes:) Initializes and returns a query object with the specified query string and item attributes. ``` convenience init(queryString: String, attributes: [String]?) ``` ## Return Value An initialized query object. ## Discussion - queryString: A formatted string that defines the matching criteria to apply to indexed items. To learn how to construct a query string, see [Create a query string for your search](/documentation/CoreSpotlight/searching-for-information-in-your-app#Create-a-query-string-for-your-search). This parameter must not be `nil`. - attributes: An array of strings that represent the attributes of indexed items. Each string corresponds to a property name that your app can set for an item; for a list of possible properties, see [`CSSearchableItemAttributeSet`](/documentation/CoreSpotlight/CSSearchableItemAttributeSet). Passing `nil` for this parameter means that the query doesn’t use attributes to find matching items. ## Discussion After you create and initialize a query object, and call [`start()`](/documentation/CoreSpotlight/CSSearchQuery/start()) to begin the query, you can’t update or reuse the query object for a new query. --- Copyright © 2026 Apple Inc.
