YaCy (read "ya see") is a free distributed search engine, built on principles of peer-to-peer networks. Its core is a computer program written in Java distributed on several hundred of computers, as of September 2006, so-called YaCy-peers. Each YaCy-peer independently crawls through the Internet, analyses and indexes found web pages and stores indexing results in a common database which is shared with other YaCy-peers using principles of P2P networks.

  • YaCy (read "ya see") is a free distributed search engine, built on principles of peer-to-peer networks. Its core is a computer program written in Java distributed on several hundred of computers, as of September 2006, so-called YaCy-peers. Each YaCy-peer independently crawls through the Internet, analyses and indexes found web pages and stores indexing results in a common database which is shared with other YaCy-peers using principles of P2P networks. Compared to semi-distributed search engines, the YaCy-network has a decentralised architecture. All YaCy-peers are equal and no central server exists. It can be run either in a crawling mode or as a local proxy server, indexing web pages visited by the person running YaCy on his or her computer. (Several mechanisms are provided to protect user's privacy). Access to the search functions is made by a locally running web server which provides a search box to enter the query and returns results of the search in form of a web page as usual on other search portals and enginesThe program is released under the GPL license.

  • Yacy es un buscador, que utiliza una red peer-to-peer como infraestructura. No hay un servidor central de control, en lugar de ello, todos los participantes son iguales. Cualquier nodo de la red puede indexar la red y ser un robot de búsqueda. También puede indexar la navegación del usuario que registra las páginas visitadas (por supuesto, no se indexan las páginas que puedan contener información privada como formularios o las páginas en protocolo https). El programa es software libre bajo licencia GPL. (es)
  • YaCy è un motore di ricerca, costruito sui principi del peer-to-peer . Il suo nucleo è un programma scritto in linguaggio Java distribuito nel Settembre del 2006 su diverse centinaia di computer cosiddetti YaCy-peers. Ogni YaCy-peer naviga indipendentemente su Internet, analizza e archivia le pagine web e registra le pagine trovate in un database comune condiviso con tutti gli altri YaCy-peers. Lo YaCy network ha un'architettura decentralizzata. Tutti gli YaCy-peers sono uguali e non esiste un server centrale. YaCy gira sia in modalità crawler, o come un server proxy locale, indicizzando le pagine visitate dagli utenti. Svariati meccanismi esistono per tutelare la privacy degli utenti che usano YaCy. L'accesso alla funzione di ricerca ha luogo mediante un web server locale, che fornisce una finestra per l'inserimento della stringa di ricerca, e restituisce i risultati su interfaccia web, in modo analogo agli altri portali e motori di ricerca.

  • YaCy (von Yet another Cyberspace, homophon zu engl. ya see) ist eine Suchmaschine, die nach dem Peer-to-Peer-Prinzip – kurz P2P – arbeitet. Dabei gibt es keinen zentralen Server, sondern alle Teilnehmer daran sind gleichwertig. Jeder Peer-Betreiber kann im YaCy-Netz suchen und zum Index beitragen. Letzteres indem er einen Webcrawler losschickt oder einfach alle besuchten Seiten über den YaCy-Proxy indexieren lässt. Wenn nun irgendein anderer Peer im YaCy-Netzwerk eine Suche startet, kann er alle von anderen Peers indizierten Seiten finden, die zum Zeitpunkt der Suche online sind. Durch das dezentrale Prinzip ist YaCy resistent gegen Ausfälle. Das Projekt YaCy wurde von Michael Christen im Jahr 2003 gegründet. (de)
