Year 1 - UE 02 - Search Engine Optimization

All the "public and popular search engines" are made of proprietary solutions. It means that except the companies who are building those search engines know how they are working.

This is very frustrating as you never know really the data they are collecting about you and what the search engines is considering in terms of results.

By chance, some people on earth decided to create projects which are open source for which you can know how the search engine is made.

In this course we will introduce you to YaCy, an open source search engine released under the GPLv2 license: https://github.com/yacy/yacy_search_server/blob/master/COPYRIGHT
