When a keyword is input, an acquisition unit (101) sorts attributes associated with products matching the keyword by the quantity of products associated with the attributes among the products matching the keyword, and acquires the attributes having at least a predetermined rank. A determination unit (102) determines whether or not the attributes acquired by the acquisition unit (101) satisfy predetermined conditions. A presentation unit (102) presents the products associated with the attributes having at least the predetermined rank among the products matching the keyword when it has been determined that the attributes acquired by the acquisition unit (101) satisfy predetermined conditions. |
