Absolutely, search is the best way for users to find their interests and communities. Solving the search problem may require all relays to support text retrieval by default. Currently, only relay.nostr.band has text structured data retrieval support. Most relays only support public key and post ID retrieval. Our just-launched #Freerse is powered by nostr.band, which allows users to discover posts, users, and communities through text search, so that all users can find their communities and stay. But the data connection is not very stable.
