摘要：
Disclosed is a system in which an index registration unit registers an index, which will be used for search processing, as a partitioned index which is partitioned on a time series basis, and a search means reads indexes older than a specified point in time, which is used as a search base point, to perform search processing, thereby searching for information based on a point in time in the past.
