My main search engine is Mojeek, and my secondary search engine is Kagi. I’ve paid for Kagi for over a year, and it gets good results. I think it’s great that every part of both search engines work without Javascript, and that Kagi’s results pages are very light. It’s also cool that it returns results for pages in the Internet Archive, which can be useful for certain esoteric topics. I’m de-ranking certain sites so they’re pushed to the bottom of results, like quora, twitter, w3schools, and reddit.
There are also no ads! At all! I used Duckduckgo in a VM today and it was dreadful how far you have to scroll just to get past the ads and see the actual results.
Kagi gets great results. My only problem is that, just like Duckduckgo, they use the Bing API. Now, Kagi actually uses their own non-commercial index Teclis, combined with their news index Tinygem, as well as calling Google’s API and many other search engine APIs (including Mojeek). My main search engine is Mojeek because they use their own index.
I’ve found Kagi great for technical/日本語 queries, which is something Mojeek doesn’t handle well. If I want to learn about a certain topic, I search Wikipedia directly. I think Kagi is the nicest and fanciest Bing/Google proxy around, with easily the best user experience of any search engine.
