How do I search through RHEL repos?

Hello.

I'm looking for 'duplicity' package for RHEL7.
I have 126 repositories in subscription-manager, but how do I search through them?
"subscription-manager repo" does not have an option to search for a package.
"yum" will search only after I add a with subscription-manager.
Repos names does not help.

Btw, search on access.redhat.com fails to search for "duplicity" even when I put the search term in quotes, it finds lots of "duplicate" words.
