A server system (10) searches for information on other products in relation to a question regarding a specific product, according to the following procedure. (1) A product ID and a query (text) pertaining to a question are input (S405). (2) A product name corresponding to the product ID is extracted from product basic information (Fig. 2 (b-1)) in an auction database (12) (S410). (3) The product name and the query are analysed and one or a plurality of keywords are specified (S415). (4) A search condition for searching for products in relation to the specified keyword(s) is set (S420), and required items of product information that satisfy the search condition are extracted from the product basic information, display information and product price information (Fig. 2 (b-1), (b-2), b-3)) in the auction database (12) (S425).
