I see that "someone needs to search" for a community for it to appear in the search bar. Furthermore, if I go to "lemmy.world/c/[email protected]", I can see and subscribe to that instance just fine.
I'm just worried about discoverability. How was I supposed to even discover [email protected] if this instance didn't know about it?
When you do the search in your instance, sometimes it works better to search for (for example) "https://programming.dev/c/programming" instead of "[email protected]". Using the full URL seems to work better. I don't know why. And sometimes you have click search more than one time for it to show up.
Yeah, looks like I just didn't wait long enough after hitting the "Subscribe" button. I guess Lemmy.world has queues and tasks and a bunch of background processing before things show up in Search.
