User search method, user search system, and user search device in a social network

摘要

[PROBLEMS] To improve the effectiveness of search results. A client 21 detects transmission of a search command by a client user X, obtains geographical position information of the client user X, and searches a server 22 including the geographical position information of the client user X and a user identifier. Send a request. The server 22 stores search request information including the geographical position information and user identifier of the received search request, and the reception time when the search request is received, and satisfies various search request information stored previously. It is determined whether or not the search request information exists, and if there is search request information that satisfies the requirement, information related to the user corresponding to the search request information that satisfies the requirement is returned to the client 21. The search request information that satisfies the requirement satisfies the condition that the time interval between the reception time in the search request information that satisfies the requirement and the reception time when the search request transmitted by the client 21 is received is less than the first threshold. .
