Patent number: 11582179Abstract: In an example information search method, if a first terminal performs a first search based on a first keyword, and does not obtain a result, the first terminal generates a request for performing a second search, and sends, to a network device, the request for performing the second search. The network device sends a second request to a second terminal. The second terminal performs the second search based on the first keyword, obtains a second search result, and sends the second search result to the first terminal. Through this technique, it can be effectively ensured that a user finds a search result corresponding to the first keyword, and that user privacy is also ensured.Type: GrantFiled: November 15, 2017Date of Patent: February 14, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yongfeng Tu, Wenmei Gao
