This is the version of PeARS for use in a federated context: admins create PeARS instances that users can join to contribute to the index. Federated can also be used as a private, single-user search engine when installed locally.
PeARS - the People's Search Engine
PeARS is an open-source, curated search engine that lets you take control of your search. It has privacy and energy efficiency at its core.
Federated search
Federated search retrieves information from a variety of sources via a search application built on top of one or more search engines.[1] A user makes a single query request which is distributed to the search engines, databases or other query engines participating in the federation. The federated search then aggregates the results that are received from the search engines for presentation to the user. Federated search can be used to integrate disparate information resources within a single large organization ("enterprise") or for the entire web.
Federated vs Indexed Search: Key Differences and Use Cases
Learn how federated and indexed search work, their pros and cons, and how AI enhances both techniques to power fast, secure, and scalable enterprise search across your tech stack.

New demo version of atsearch.network is here 💃 quick recap: any AT Proto app can invent its own record type: scrobbles, books, photos, RPGs, etc... nothing searches across them so i built a search engine that reads your lexicon and figures out how to index you
