Searsia is a protocol and implementation for large scale federated web search.

Searsia provides the means to create a personal, private, and configurable search engine, that combines search results freely from a very large number of sources. Searsia enables existing sources to cooperate such that they together provide a search service that resembles today’s large search engines. In addition to using external services at will, you can also use it to integrate whatever private information from within your organisation - so your users or community can use a single search engine to serve their needs.

Searsia is an open source engine and a protocol, created by academic researchers. Using Searsia you can :

  • Manage and share large collections of independent sources;
  • Select for each query the most relevant sources;
  • Combine sources in an aggregated search interface;

Searsia learns over time what kind of information each source provides. To see it in action check the search engine of the University of Twente that combines the results of about 30 sources, including results from Google's web crawl, from Courses, from News, the Telephone directory, the Timetables, as well as results from social media, such as Facebook, Twitter, Pinterest, and Flickr.

The Searsia software is open source and available via:
