Love this website too. But in this case the database and search engine is hosted on the server, it only uses IPFS to distribute a copy of a folder ready out of the box (db included) to be hosted as another instance (a backup).
You actually should be able to access it using IPFS at/ipns/torrent-paradise.ml or /ipns/12D3KooWB3GY1u6zMLqnf3MJ8zhX3SS1oBj7VXk3xp6sJJiFGZXp but it seems that clicking search throws an JS error :/
