How to make artifacts searchable in

I have a few clarifications regarding Using the above link, I could able to find the available artifacts in different public repositories. My requirement is, I have artifacts uploaded in my hosted nexus 3 repository and I would like to make those artifacts searchable in the mentioned maven search engine.

It is mentioned here that my library must be present in the official repository to be listed in mvnrepository site. I would like to know any do we have any other options to make artifacts hosted in my nexus 3 repositories to be searchable on this site ?

Please share your suggestions.
