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?

    Even the main search engines don’t index the entire internet of content these days and their databases are truly massive already. Writing a basic web crawler to produce a search index isn’t all that hard (I used to do it as a programming exercise for applicants) but dealing with the volume of data of the entire internet and storing it to produce a worthwhile search engine however is just not feasible on home hardware, it would be TB’s at least. It wouldn’t just be a little worse it would dramatically worse unless you put substantial resources to it including enormous amounts of network bandwidth which would have your ISP questioning your “unlimited 1 gbps fibre” contract. It would probably take years to get decent and always be many months out of date at best.

    Doesn’t seem practical to try to self host based on the need to download and index every single page of the internet its a truly massive scale problem.
