Congratulations.
Truly impressive search results.
I tried two, one word searches. The results were interesting, useful, and would have been impossible (well, really really hard) to find, on standard search engines. Plus, no garbage, ads, recommendations, etc etc.
As another commenter suggested, it is what World Wide Web searches results were like, twenty years ago!
PS. I added Marginalia as a search option (even the default for now) in Firefox Nightly (on Android).
In case others want to, under settings for search, you can add other, then name, and then:
https://search.marginalia.nu/search?query=%s
I am running Linux Mint, and I did not expect adding a custom search engine to be missing from Firefox. There are plug-ins, but I don't like adding plugins.
Open a search, right-click on the address bar. The author added the magic metadata needed, so Firefox should be able to pick it up and offer "add search engine" option in the context menu.
I know. It's an idiotic UX regression over being able to configure search engines yourself in the Settings screen. Takes control away from the user.
