Is there a way to search for all communities in a given server?

So for instance I'm interested in all communities in the aussie.zone instance, and I can't find a way to use the search function for that. I've tried searching for communities using the search string "aussie.zone" and I get nothing.

Then in the screenshot shown I tried searching for communities with just the string "aussie" and I got "Aussie Environment@aussie.zone", which is strange because all the community names there contain the substring "aussie" and I'd expect this search to find them.

Is this a bug? Am I doing it wrong? It would be nice if there was a way to browse all communities in a given instance easily, because when I find an instance I like, I want to be able to go through and find the communities I like just as if I was browsing local communities on this instance.

Also the copy-paste method, which is still extremely clunky, is broken for me. I it just has [email protection] which when clicked does nothing useful. I've tried the Lemmy Link addon but not only is that also a very slow and clunky method which still doesn't let me browse by server, it keeps slowing down firefox so I've had to uninstall it.
