I'm still flabergasted by the fediverse sometimes. I search for libreoffice in my mastodon client and one of the results is "libreoffice@lemmy.ml" and even a peertube instance.

If the mastodon instance you are on doesn’t know about LibreOffice’s account, then it won’t show. You will have to search for their handle/username like this: @libreoffice@fosstodon.org

This is mostly a problem on smaller instances. The bigger an instance is, the more connections to other instances it has.

You have to understand that federation doesn't happen instantly. Your server has to sync with the other instances before you can find the account you're looking for.
