Rebuild search with trust

Posted on January 20, 2024

Finally there is a thing people can agree on:

Apparently, Google Search is not good anymore. And I’m not the only one thinking about decentralization to fix it:

Honey I federated the search engine - finding stuff online post-big tech - a lightning talk at the recent chaos communication congress

The speaker however did not mention, that there have already been many attempts at building distributed search engines. So why do I think that such an attempt could finally succeed?

My definition of success is:

A mildly technical computer user (able to install software) has access to a search engine that provides them with superior search results compared to Google for at least a few predefined areas of interest.

The exact algorithm used by Google Search to rank websites is a secret even to most Googlers. However I assume that it relies heavily on big data.

A distributed search engine however can instead rely on user input. Every admin of one node seeds the node ranking with their personal selection of trusted sites. They connect their node with nodes of people they trust. This results in a web of (transitive) trust much like pgp.

Imagine you are searching for something in a world without computers: You ask the people around you and probably they forward your question to their peers.

I already had a look at YaCy. It is active, somewhat usable and has a friendly maintainer. Unfortunately I consider the codebase to not be worth the effort. Nevertheless, YaCy is a good example that a decentralized search software can be done even by a small team or just one person.

I myself started working on a software in Haskell and keep my notes here: Populus:DezInV. Since I’m learning Haskell along the way, there is nothing there to see yet. Additionally I took a yak shaving break to learn nix.

By the way: DuckDuckGo is not the alternative. And while I would encourage you to also try Yandex for a second opinion, I don’t consider this a solution.
