DC Search

A very brief overview of the search engine on the file sharing network Direct Connect.
Subj walks around the main hublists and currently knows about ~ 740 million files.

dc.proisk.ru

You can ask like this:
dc.proisk.ru/?q=house+m+d - well, you understand
dc.proisk.ru/doom2.wad - by the specific file name
dc.proisk.ru/U3TDHJ3WAQZKSBQNF4GIFSRRTDBMTKFX6LGSHVA - by tth

And even like that:
U3TDHJ3WAQZKSBQNF4GIFSRRTDBMTKFX6LGSHVA.dc.proisk.ru

Or click on "clarify" and enter a query of any complexity.

Yes, any dc client has its own search. But not everything can be found on your favorite hubs.

Dessert:
dcstat.proisk.ru/?query=queries+top+tth- top downloads today for several major hubs
dcstat.proisk.ru/?query=queries+top+tth&period=w - for a week

All these things are open source, with some desire and skills you can put and set on your favorite hubs.
