PROBLEM TO BE SOLVED: To provide technique for carrying out retrieval processing efficiently. SOLUTION: In the subject inspection information retrieval device 400, a retrieving style setting part 706 sets a plurality of retrieval styles based on setting instruction from a user. A logic operator setting part 708 sets a logic operator between the retrieval styles based on condition-deciding instruction from the user. In this case, the logic operator setting part 708 decides the logic operator based on the number of times of clicking a mouth by the user. Whenever the user clicks the mouth selecting the retrieval style, the logic operator setting part 708 switches the logical operators of at least AND and OR periodically, and decides the logic operator depending on the number of timed of clicking the mouth to the retrieval style.
