Distributed search engine

A distributed search engine is a search engine where there is no central server. Unlike traditional centralized search engines, work such as crawling, data mining, indexing, and query processing is distributed among several peers in a decentralized manner where there is no single point of control.

History

InfraSearch

In April 2000 three programmers (one of them was Gene Kan) built a prototype P2P web search engine based on Gnutella called InfraSearch.[1] It was meant to run inside the participating websites' databases creating a P2P network that could be accessed through the InfraSearch website.[2][3][4]

Opencola

On May 31, 2000 Steelbridge Inc. announced development of OpenCOLA a collaborative distributive open source search engine.[5] It runs on the user's computer and crawls the web pages and links the user puts in their opencola folder and shares resulting index over its P2P network.[6]

YaCy

On December 15, 2003 Michael Christen announced development of a P2P-based search engine, eventually named YaCy, on the heise online forums.[7][8]

FAROO

In February 2001 Wolf Garbe published an idea of a peer-to-peer search engine,[9] started the Faroo prototype in 2004,[10] and released it in 2005.[11][12]
