A search method includes obtaining, by a first terminal, a first key word from a user; searching, by the first terminal based on the first key word, the first terminal for a first search result associated with the first key word; sending, by the first terminal, a first search instruction to a second terminal (the second terminal is a terminal in a device group to which the first terminal belongs), where the first search instruction carries the first key word, to trigger the second terminal to search the second terminal for a second search result associated with the first key word; obtaining, by the first terminal, the second search result from the second terminal.
