The way global queries on our filter work is to only pull events from your follows+their follows network (filtered). When your client requests a note, a profile, available direct messages, or a channel, we pull all of the available related content from our aggregator (unfiltered).

You won’t see *everything* from that public relay, but you’ll see a wide enough network to fully populate your global feed. If you have a very large follows+their follows network, we randomly sample from it each time you refresh your global feed.
