Hey there!

I'm quite new to the fediverse and got a question. On the instance I am, I can e.g. search for the community [email protected], which is being found and I can join it bla bla bla (or, as you see, post in this community here).

But when searching for example for [email protected], my instance says that it cant find anything.

Is this intended behaviour and how do I know why it cant find it?
