WHAT IS THIS?



YaCy is a search engine for the Web (supporting also ftp).

It is neither a search portal nor a portal software but a peer-to-peer

software that works on principles similar to file sharing.

The difference is that you do not share any kind of data but web indexes.

YaCy also generates the indexes it organizes. YaCy is a web crawler for 

everybody, without censorship and central data retention:

- search the web (automatically using all other YaCy peers)

- co-operative crawling; support for other crawlers

- intranet indexing and search

- set up your own search portal

- all users have equal rights

- comprehensive concept to anonymise the users' index

To be able to perform a search using the YaCy network, every user has to

set up their own node. More users are leading to higher index capacity

and better distributed indexing performance.
