Interesting. I hadn’t even thought about how the fact that instance1.[post] and instance2.[post@instance1] is essentially the same thing and how search engines would handle it. Interested in what you come up with!
I imagine that would be quite inconvenient… Especially as Lemmy grows and has potentially many more instances.
But what if the post I’m searching for is not on lemmy.world? Say the instance doesn’t even have Lemmy in their name, like beehaw.org. How would a search engine index it? How would it know it’s part of Lemmy?
You should look into ReVanced :)
