Abstract: Described is a system that may search for content items in response to a voice-based natural language query. The system may provide search results for content associated with various types of user actions such as sending or receiving a document, sharing a content, printing a document, etc. For example, the system may provide search results to a query such as “Show me the last spreadsheet I sent to Bill,” or “Find all emails from Bill in April.” In addition, the system may search for content associated with a particular application. For example, the user may provide a search query including “Open my ‘NewApp’ documents.” Accordingly, one or more aspects of the system may provide an intuitive search mechanism for content by allowing a user to provide natural language search queries.

Abstract: A method of implementing challenges in single-player games starts with a server receiving a challenge from a first mobile device and transmitting the challenge to a second mobile device. The challenge may include a high score or an achievement of a single-player game obtained on the first mobile device, The server may determine that a new high score is obtained on the second mobile device that is equal or greater than the high score included in the challenge or that the achievement is completed on the second mobile device. The server may then transmit a notification to the first mobile device that the challenge has been completed. If the server determines that the new high score is obtained, the notification may include a new challenge from the second mobile device to the first mobile device and the new challenge may include the new high score. Other embodiments are also described.

Abstract: In accordance with the present invention, a method and apparatus that provides software products for installation on a user terminal is provided. The method begins by receiving over a communications network a user selection that includes a choice of a plurality of user-selected software products to be downloaded. In response to receipt of the user selection, an installation guide is assembled that includes installation instructions associated with each of the user-selected software products. A single user command is received over the communications network that includes a request to begin downloading the user-selected software products. In response to the request, the user-selected software products and the installation instructions are sequentially downloaded over the communications network to the user terminal.

Abstract: A system provides targeted advertising to customers of an application while preserving the confidentiality of the customers' application information. A marketing system provides a marketing engine that executes on a computer system of the customer of an application and provides targeted marketing to that customer. Since the marketing engine executes on the customer's own computer system, it may have access to the customer's application information. The marketing engine can analyze the application information and provide marketing information that is targeted to the customer without compromising the confidentiality of the customer's application information.
