Abstract: Various techniques for selecting electronic messages based on user data residing on user devices are described herein. In one embodiment, a method performed by a computing system includes receiving a search query via an input device of the computing system, transmitting the received search query to a server, and receiving a set of electronic messages from the server in response to the transmitted search query. The method also includes selecting a subset of the received electronic messages at the computing system based on user data residing on the computing system. The selected subset of electronic messages are then displayed via an output device of the computing system.
