Awesome. I think there's a huge need for a search engine filtering out commercial content. It's basically just all spam.
Recently I wanted to find information on hacking a device I had obtained - but of course any search query I could throw at search engines only yielded ways to buy it or low-effort reviews. I tried marginalia but it seems like the index wasn't quite large enough for my purpose yet.
May well be that what you were looking for is in the index. My algorithms have a lot of potential for improvement. Right now they only really work well for broad topical searches. They are also entirely blind to some fairly rich websites, such as certain types of forums.
Consider trying Kagi. (I first started using it while it was still in closed beta, but I am not otherwise affiliated with them. I am very satisfied with it so far.)
I also used it during its beta phase and found it rather unremarkable. What really kept me from seriously considering it is that the account requirements prevents using it anonymously.
