Lemmy Support

I created a community few hours ago !skypictures@lemmy.ml on lemmy.ml. It currently has two post and two subscribers. I wanted to check if it is discoverable through search. While you can find the community through this home instance, but it doesn't show up through others like beehaw.org or browse.feddit.de.

Do I need to do something manually? Or it would do the indexing(?) on its own? If so, it would be great if someone tells me how much time it generally takes. Thanks.
