## Abstract

An information processing apparatus retrieves related search criteria that are related to given search criteria, from a search criteria history storage. The information processing apparatus retrieves first search results matching the related search criteria. The information processing apparatus retrieves second search results matching the given search criteria. The information processing apparatus identifies selection criteria, based on operation logs corresponding to the related search criteria. Based on a comparison between third search results and fourth search results, the information processing apparatus generates distinction information that indicates a distinction of the fourth search results. The third search results are among the first search results and identified based on the operation logs. The fourth search results are among the second search results and correspond to the selection criteria. The information processing apparatus provides the distinction information.
