PROBLEM TO BE SOLVED: To enable a program using records acquired from an RDBMS operating in an embedded device, or the like, for quickly retrieved from the number of hits and a record located at an arbitrary part of a search result. SOLUTION: A search device 100 divides a SEARCH start request indicating a search condition, and the like, issued by an application 110 into processing to retrieve a record number that meets a search condition and a processing, by using the record number obtained by the retrieval as a retrieval condition, to retrieve a column designated by the application 110. The search device 100 first executes the processing to retrieve the record number, retrieves the record number of a record that meets the retrieval condition from the RDBMS 120, while ranking the record number, and notifies the number of hits to the application 110. Then, the retrieval device 100 retrieves data from the RDBMS 120 by using a record number at a rank specified by the application 110 as the retrieval condition, and returns the data to the application 110.
