is there any way to know what happened on the search engine / index on gemini ? I love frugal but when I tried castor (rust gui) I was just a bit too confused by the ergonomics (both of search and navigation). I'm pretty open minded (I use gnu ed .. so esoteric or different doesn't bother me) but it was too much of a regression compared what we're used through http clients.
