Implemented by #19361 already?

Surprise! If I don't ask, maybe never find this option.

You just made me write a PR to remove this option as it is useless.
Will create it once I've been able to test that it still works as expected :)

See #21962.

I mean completely excluding the fork repository. Just like github

move discussion from

• Remove ONLY_SHOW_RELEVANT_REPOS setting #21962

gitea never be found on the explore page.

you means gitea is a fork of gogs, it will never be display on search result.

This can be avoided in practice by creating a new repository. In fact, gitea does the same thing. The goal of fork is more like contributing to the core repository
