@ololduck whenever you follow, reply, like etc a user or toot from another instance, the communication that happens in the background to facilitate that is the 'federation' that 'just happens'
so as an example, aiui, once you follow an off-instance user, your instance sends a notice that you want to follow that user, and starts to get notified of new posts by that user in future, so that they can be pulled in and presented to you in your local feed
@ololduck searching hashtags will only work for content that your instance would otherwise have seen, so if you're on a single user instance, you'll only see results for hashtags for posts that were already in your feed as that is the totality of the posts your instance knows about.
OTOH when you post with a hashtag, that post is visible to people searching that tag on all instances where at least one of their users already follows you, as your posts are federated to their instance already.
Have a good one!
@ololduck for really small instances there is the option / notion of feed "relays" so that you inherit a donor instance's 'firehose' of global content without having to actively follow a bunch of people, which gives you an enriched 'starter pack' of global activity based on what *that* instance sees in it's global timeline.
@ololduck https://wisechecker.com/mastodon-hashtag-federation-why-some-tags-are-sparse/ seems a reasonable write up in fuller detail
@ololduck Fedi.tips is pretty thorough, see eg

https://fedi.tips/why-does-someones-account-page-look-completely-blank-is-it-really-blank/
and probably the detail you want:
