摘要：
A distributed information retrieval system in which the central computer is connected to a plurality of terminal devices and the management information includes a set of retrieval keys kept on the central computer side where the primary retrieval is achieved. The secondary retrieval thereafter is executed on the terminal side to reduce the load imposed on the central computer and to improve the response time for forwarding an answer to the user of the retrieval system.
