Is it possible to fetch metadata of torrent without the knowledge of Infohash?

Let's just say I bootstrap into the keyspace and I start discovering nodes that are close to me. Can I fetch metadata of various torrents other DHT nodes may have in their DHT storage without having knowledge of Infohash. Is it possible to issue a request to all the DHT nodes in my routing table to give away all the metadata they are responsible for holding.

By metadata I mean, every DHT node is responsible for holding Infohash closest to them, displayname(with some other info) and the list of peers downloading that torrent. If it can be made possible then it would become possible to build a torrent site overnight from scratch by crawling the dht nodes even if every other torrent site along with their backups and tracker server were shut down by an adversary.

The request would be like give me whatever you are storing "because I want to index it and I don't have infohash".

An individual node may or may not actually have the torrent metadata, even if it has the infohash in its routing table.
