While typing the title i found some existing posts, but they don’t really answer the question as well as I’d like.
The typical recommendation is to use some external web page that is not actually a lemmy instance.
This means if I’m using lemmy from within an app I have to pop into a web browser, find what I’m after copy anything needed to clipboard and pop back into the app ready to paste / re-format / search.
This sounds really not streamlined.
Other solution is to have a couple of accounts and flip between them and search each home instance for what I’m after.
I’m not sure I’m clear on what I’m asking so i’ll give an example…
I’m on lemmy.world, there is a community on lemmy.radio/c/amateur_radio Let’s assume i don’t know this however.
a) How would i find this while logged into the lemmy.world website? b) How would i find this while logged into the lemmy.world via an app?
If this functionality does not exist that’s fine, but all I’ve heard about federation makes me think it does exist and i haven’t found it or don’t understand it (hence why i think I’m asking a dumb question).
Is there a foolproof legitimate way to browse or search a list of communities on another instance without going to that instance or using a third party site?
What app are you using? If you’re on iOS, I know the Voyager app allows for selection of filtering your search to Communities, Users, Posts, etc. and Lemma has a pretty good smart search that has found the communities I was looking for.
As far as I am aware, at least one user on your instance needs to be subscribed to a community on a different instance or at least specially searched for it to be searchable. In your case, if no one on lemmy.world is subscribed to or specifically searched for lemmy.radio/c/amateur_radio, you wouldn’t see it on a search from you lemmy.world account. Otherwise you’ll need to use a browser to find the community and seek it out on the web. Not super streamlined yet, I agree.
The only other more functional browser searches that I know of are:
https://lemmyverse.net/ and https://browse.feddit.de/
lemmyverse is my go to for finding both communities and servers.
