Abstract
The goal of this paper is to review and classify the different approaches to search in peer-to-peer networks. We then describe the approach implemented in JXTA search. JXTA is an open peer-to-peer network environment. JXTA search is a network of hubs that index the content of a peer-to-peer network. Finally, we propose an organization of the JXTA search hubs, which reduces the storage and communication requirements between the hubs.
