There is simply no usable self-hosted search engine. There are some projects like Yacy or Searxng, but they do not have their own index. And having your own self-hosted index is kind of impossible because you need to save the whole of the web on your own devices to be able to search it.
Yacy does have its own index it even allows you to crawl the webpages yourself from the settings page problem is that the results you get out of it fucking suck
I really like the concept of yacy just wish the results were better but I think there is value in p2p search indexes yacy is probably the most reasonable search engine to self host since you don't have to index everything yourself
I have had some success with https://marginalia-search.com/
Which does have its own index it is open source so you could theoretically self host but you would need to make your own index
Yeah, that's a problem. So even if you want to search your local newspaper, you won't be able to because of bot protection. Your crawler will be blocked. You also can't put the whole of Reddit or even Lemmy in your search index.
I do think this is one of the places where yacy has it's strength since yacy is p2p you can retrieve results from other nodes that have indexed the page thus large websites can be collectively indexed by many nodes.
I also don't remember having problems with the crawler getting blocked but I also didn't do a lot of crawls I can see this being a problem though.
