Can a search engine be selfhosted? - Lemmy.world

The quality of search engines has gone down so much for technical questions. I’m looking for a way to index sites like stack exchanges, reddit, quora, and research papers. Would this be possible to do this locally with metadata?

I mean, you can easily host a meta-search engine like Searx, Searx-ng, Whoogle, etc. I run Searx-ng and it sends your queries to multiple engines and shows them to you.

To host your own, you’d need to crawl and index every site. It’s certainly doable, but it would take a lot of time /effort.

I agree. Selfhosting a true search engine is way too much work and infeasible for individuals. Meta search engines however are very feasible and a great option.
