Abstract: This product search server is provided with: a WEB server which communicates with an exhibition terminal and a product search terminal; a control unit which performs processes in response to a request such as product offering, search, order, etc.; a clock which holds and returns the current time; an product-offering DB which accumulates offered-product information, registration time, latitudes and longitudes of registration places, and contact information of registrants; and a mail server which transmits order notification. With this structure, the offered product of the entry is displayed only when the distance (unit: kilometer [km]) from the entry registration place to the search place is less than the square value of the elapsed time (unit: hour [H]) from the entry registration to the search, so that the searcher located at a shorter distance from the seller can acquire the right of order earlier.
