Kagi, unfortunately, is getting worse too. I think mainly because they don’t get access. But I’m not sure. I had to fallback more and more to Google, because Kagi couldn’t find exact matches, while Google could. Like texts which I copied from a webpage (for example from Android’s source), and it can’t find it.
Its search results ordering is quite good, but the accessible information for them seems to be shrinking. And quickly.
I’m at the point where I don’t search for complex things anymore. I use Kagi for things which can be found with any search engines. Not because I chose it, but because I was forced. This was not the case a few years back, when I started to use it.
Btw, there was one thing with which Google was superior all along: define <word>. And they fucking killed it in the past months, for a far, far worse solution. Nothing comes even close.
