Have tried out SearxNG without self-hosting, via different instances, but had to abandon it as it is way, way beyond my mental capabilities to get it to work.
I doubt I could manage to self-host, having looked into Docker for some other matter.
Using Mojeek currently, which isn’t great but not too terrible.
Well, it worked initially, then more often than not my searches produced no results or confusing error messages.
Experimented a lot with the SearxNG settings, and also with my browser and firewall settings in case there was some issue there, and eventually gave up.
I was unable to find information online about the issues I experienced, in part because I had no idea how to describe them in order to find help.
Think I tried it in three different browsers, over the course of a month or so, but primarily in Firefox.
