Why BitCommet can't search for files?

I'm wonder, before years we had the slowest turtle called 'emule', it was pretty crappy though, But it has a greate feature, it has file search via the Kademlia.
If I understood currectly, torrent replacement for Kademlia is DHT.
So why we can't we share a directory and search in it like oldschool Emule did?
Thanks in advance!
