A distributed architecture and indexing algorithm for high-performance information retrieval has been developed. A prototype system has been built that achieves a throughput of 500 queries per second with a response time of less than one second on an 8-node network of workstations. The algorithm is robust in the presence of lost and duplicated messages as well as failures of nodes of the network. The architecture can be scaled up to larger networks and higher levels of service. The retrieval model allows for semantically rich queries and information objects.
