A computer-implemented search method includes receiving a registration request from each of one or more computer applications installed on a computing device and registering the applications in response to the request, wherein the registration request indicates an intent by the application to receive search query information from a search application associated with the device. The method also includes receiving user input on the device in the form of a query, providing the query to the one or more registered applications, receiving responses from the one or more registered applications that include data that is managed by the one or more registered applications; integrating the responses into a result set; and presenting the result set with the computing device.
