That only works if they're actually discoverable when you search for them, so you can pick the correct one. On reddit if you search for a specific thing, you get a list of all possible subreddits in one go. On lemmy... it really depends on the instance you're on, and if anyone else on your instance has discovered the other communities yet. You never know if the search results are complete. Even https://browse.feddit.de is not always showing all the communities I noticed.
And even now I have to keep rechecking communities/interests I have already subscribed too because new duplicates get made all the time with new instances showing up.
