And to clarify some of the things that came up in this thread: ants is just a search interface, independent of any specific clients or relays.

If search is required to resolve a query it will hit NIP-50 relays exclusively, depending on what kind of relays you have in your relay lists (that’s why logging in is a good idea). It defaults to nostr band and other bigger relays, but if you run nostr-relay-tray or other personal or local relays it can (and will) search those too.
