How do you search? There is no search engine for it?
IPFS is kind of like the BitTorrent DHT. Every file is indexed by a cryptographic hash and can represent anything. There is no general way to search it, but you can build an index and search the index like how torrent search engines work.
This is also what i dont understand. I thought there should be a indexer but i never found one.
Look how decentralized LibGen on IPFS does it.
