Abstract
The invention provides an information retrieval system wherein, even when a plurality of data bases are retrieved simultaneously, information retrieval can be performed at a high speed without necessity for special hardware and without being influenced by the magnitudes of the data bases of a retrieval object. The information retrieval system includes a plurality of retrieval servers for performing retrieval processing, and a retrieval management server for managing operation of the plurality of retrieval servers. The retrieval management server is constructed so as to divide a data base of a retrieval object and relating information regarding the data base and allocate resulting divided parts of the data base and the relating information corresponding to the divided parts in sets to some or all of the plurality of retrieval servers. The plurality of retrieval servers are constructed so as to perform information retrieval for the divided parts of the data base allocated by the retrieval management server parallelly to and independently of each other.
