I'm curious because I go through this experience a little more often than I'd like to admit, and typically end up frustrated and without any results (admittedly without using Kagi, yet). Did you just search for a phrase from the video, or what did you do to find what you needed with Kagi?
I've not gone looking for videos specifically, but my experience there is that Kagi seems to focus on what you've explicitly searched for, where Google and others have increasingly leaned into interpreting your intent.
Google's approach works well enough when you're searching for a commodity and you don't care terribly much about the specific source. I get the impression Google, especially post-LLM, wants to divorce satisfying your question from the underlying sources.
I find Kagi is better at finding a specific thing, especially if you're willing to engage with it as a tool, ye olde search engine style. If my query doesn't find what I want, it's usually apparent why and I can reframe it.
Yes and no. Because of aggressive action from IP holders a lot of these sites went underground and deliberately aren't indexed in the US and EU but providers from Russia or Switzerland got shadowbanned.
