I tried "apache cassandra" with yahoo and duckduckgo and they both have similar ads that look like search results. Yahoo is even worse, as they just have "Ads related to: apache cassandra" at the top, and then a bunch of ads, where is isn't really obvious where the actual search results begin, just a horizontal line.
Having a look for other search engines, I see all the regular ones from the 90s seem to be dead. There is one called swisscows.com which I hadn't heard of, and it has similar inline ads.
Those are exactly the same top two results, in the same order, as the Brave search screenshot you're responding to. Perhaps you meant to respond to another comment?
The wiki link is second in Brave also, or are you pointing out something else?
Anyway, I also advocate for Kagi, but Brave happens to be free, and I haven't been convinced of the value of what Kagi charges for search, but I have been tempted.
Brave browser tries to do some annoying crypto thing by default and has some questionable privacy settings but you can turn all that off. Other than that it is a great browser which has built in ad-blocking (including for youtube). The search is great and is constantly improving.
