Google returned a ton of unrelated posts and I had to tell it to stop ignoring my search terms. Kagi returned the only relevant page: a comment on a Github issue that Google wasn't able to find, and no other fluff, because that particular combination of words doesn't exist anywhere else on the Internet.
In other words, Google lies and paraphrases your search to return as much results as possible, usually not very relevant, while Kagi respects my search terms and can surface very niche pages. 2022 Google makes the Internet feel very small.
I've test driven Brave Search for months as well, and this is my personal ranking, from best to worst: Kagi > Brave Search = Google Search > DDG.
