Has anyone checked out marginalia search?

This is not an ad BTW, I literally stumbled upon it a few minutes ago. From what I can gather, however, this is a [DIY-ish] search engine that solely searches on text (no other forms of media, such as, ... idk hypertext maybe), which allows users to have more control over queries (like including and excluding terms). I suppose this would prune out most of the modern websites, but I guess some of y'all would prefer that option anyway. Has anyone else tried it out? I'm genuinely curious about more opinions on this
