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.
In April 2000 three programmers (one of them was Gene Kan) built a prototype P2P web search engine based on Gnutella called InfraSearch. It was meant to run inside the participating websites' databases creating a P2P network that could be accessed through the InfraSearch website.
On May 31, 2000 Steelbridge Inc. announced development of OpenCOLA a collaborative distributive open source search engine. 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.
Monitoring and controlling operations of urban and rural infrastructures like bridges, railway tracks, on- and offshore- wind-farms is a key application of the . The yacyinfrastructure can be used for monitoring any events or changes in structural conditions that can compromise safety and increase risk. It can also be used for scheduling repair and maintenance activities in an efficient manner, by coordinating tasks between different service providers and users of these facilities. devices can also be used to control critical infrastructure like bridges to provide access to ships. Usage of devices for monitoring and operating infrastructure is likely to improve incident management and emergency response coordination, and quality of service, up-times and reduce costs of operation in all infrastructure related areas. Even areas such as waste management can benefit from automation and optimization that could be brought in by the yacy.
