A search server (10) includes an extracting unit (15b) that extracts a search target matching a search condition based on profile data, and a transmitting unit (15c) that transmits the extracted search target to a user terminal T. The search condition includes a first frequency of appearance for each of one or more specified topics specified by a user in a first specified period and a second frequency of appearance for each of the specified topics in a second specified period being later than the first specified period. The extracting unit (15b) extracts the search target where the frequency of appearance for each of the specified topics obtained from the profile data in a first search target period is identical or similar to the first frequency of appearance and the frequency of appearance for each of the specified topics obtained from the profile data in a second search target period being later than the first search target period is identical or similar to the second frequency of appearance.
