PROBLEM TO BE SOLVED: To reduce the labor of transition processing.SOLUTION: Firstly, a search device 101 accepts a search request 121. Then, as for a record 112-1 and a record 112-4 matching search conditions, the search device 101 determines an identifier to be used for performing access to a data store #2 between a data store dependent identifier and a data store non-dependent identifier. As for the records 112-1, the search device 101 performs access to a storage area controlled by the data store #2 by using the data store dependent identifier since search frequency is high, and as for the record 112-4, the search device 101 generates an identifier showing a storage position by using the data store non-dependent identifier and information in an identifier generation rule table 111 since search frequency is low. Then, the search device 101 performs access to the storage area controlled by the data store #2 by using the generated identifier. |
