For Kagi, at least, there's a very well integrated search customization method that they didn't bother to show here. For any search result, you can add a ranking adjustment for the site it came from. This is directly in the results, so it's very accessible, and quite easy. One of the choices is 'pin', which is fantastic for technical work: 'sqlite.org' is now boosted over everything else, for me, and it's exactly what I want. I could just as easily take it out, if it becomes a problem.
