In this paper we introduce a distributed information retrieval
system using agent-based technology. In this multiagent
system, each agent has its own specific task and can
be used to handle a specific document repository. The system
is designed to automatically comply with access restriction
rules that are normally enforced in companies. It is
used in the administration offices of the German capital city
Berlin where it serves as a testbed for further research on
aggregated search in an enterprise environment with roughly
50,000 employees
