Abstract: A device implementing a system for anonymizing user data provided for server-side operations includes a processor configured to receive user input including a search term, wherein first and second data structures are stored on the device, the first data structure including user interest data items that correspond to prior user activity, the second data structure including topic data items mapped to the user interest data items, the topic data items being broader than the user interest data items. The processor accesses the second data structure to obtain one or more topic data items. The processor transmits, to a server, the search term and one or more topic data items for obtaining a query suggestion or search result. The processor receives, from the server, the query suggestion or search result, the query suggestion or search result having been obtained based on the search term and one or more topic data items.

Abstract: A device implementing a system for providing query completion suggestions includes at least one processor configured to receive a partial query, and derive one or more query completion suggestions for the partial query from content items that are locally stored on the device, each respective query completion suggestion being associated with metadata extracted from one of the content items from which the respective query completion suggestion was derived. The at least one processor is further configured to rank the one or more query completion suggestions based at least in part on the metadata associated with each of the one or more query completion suggestions. The at least one processor is further configured to provide, for display, at least one of the one or more ranked query completion suggestions.
