RETRIEVAL SERVER SYSTEM

PROBLEM TO BE SOLVED: To improve the purchase convenience of commodities by notifying the information on the tenant offering the corresponding commodity and the information including the image information on plural retrieved tenants in response to the purchase retrieval condition that is received from a client terminal. SOLUTION: A retrieval means 2 of a server 1 that is connected to a client terminal via a network retrieves a tenant index data base 5 to return and display the corresponding information (a tenant list, etc.) on the client terminal in response to the notification received from the client terminal. A cybermall display means 3 retrieves the data base 5 in response to the notification given from the client terminal and returns the visual information (virtual cybermall, etc.) which combines the image data on every tenant, for example, and displays them as a shopping center and returns the detailed visual information on some tenants designated by a virtual cybermall to display these information on the client terminal.
