A unified search system is described herein. The unified search system is configured to enable, in a control device (e.g., a remote control), a user to input a search query. The unified search system includes a plurality of content providing device interfaces configured to interface the control device with a plurality of content providing devices. Each content providing device interface is configured to receive the search query from the user input interface, format the search query according to a corresponding input device type, and provide the formatted search query to one or more corresponding content providing devices. Search results received from the content providing devices are displayed at a display of the control device and/or at another display (e.g., a television).
