Tim Lu, Shan Sinha, Ajay Sudan · 2002
The primary challenge in developing a peer-to-peer file sharing system is implementing an efficient keyword search mechanism. This paper presents Panaché, a distributed inverted index that scales well with the number of nodes in the network. Panaché addresses three critical needs for searching peer-topeer file sharing systems—efficient use of bandwidth, relevant search results and accommodation for graceful node transience. To achieve these needs, Panaché aggregates popularity information and builds upon other peer-to-peer systems that distribute index
