Hi All,
I'm having some trouble in the query department - i don't understand why querying by URN is bad in Gnutella, and what replaces it.
Say i want to find more souces for the file i'm trying to download - the simple way for me is send a query request with its URN (sha1) - i saw that LimeWire does not support this (only 1 hop) - why send a query by keywords if i'm getting alot of irrelevant answers? i know other P2P networks use the search by a unique key to limit results for mathces only.
Someone (maybe kun) told me here in this forum that querying by URN pollutes the network but i don't understand it, and that Gnutella will use DHT - so, is it used? If so, does it hash keywords as well or there it uses URN?

What's wrong with querying by URN and is it possible to do that in Gnutella?


Thanks for any help,
Snayit
