Is that how rpmfind works?
Don't know _exactly_ how I searches, but I think that point is mute.
http://rpmfind.net/linux/RPM/ What packages are available for CentOS and third party repos without having the .repo files installed?
Sorry, I don't understand. Add the few repo's you know you'll need (there aren’t that many) and execute your search. Simple. Between whatprovides and list, I find everything I need.
