@Gargron Sorry, I went off on a tangent. Yes, you answered my question.
I meant, you must be signed up on an account which can be queried by other servers on the fediverse to determine if your account is ok to have search permissions.
On the surface, I'm not sure it's possible to do something like that...
@Gargron I'm describing a potential way to allow fediverse users to search, not anonymous users. Sorry, I'm not sure why this is difficult to articulate...
