A storage unit stores a plurality of search terms. A generation unit selects two or more of the search terms. The generation unit determines a combination of search terms to be selected such that the size of the search query is equal to or less than a first threshold, and such that an estimated value of the number of documents to be retrieved by the document set management system in response to the search query is equal to or less than a second threshold.
