Bug 736696

Description of problem:
A very frequent question asked when using RHN is: "Which channel(s) should I subscribe to, to get package X, for RHEL version Y".

For example, "I am running RHEL6. Which channel should I subscribe my system to if I want to install the 'rgmanager' package?"


How reproducible:
Always


Steps to Reproduce:
1. Go to https://rhn.redhat.com/rhn/channels/software/Search.do
2. Enter "rgmanager", select "In the following  and hit "Search"
3. When shown results, click on "rgmanager"
  
Actual results:
10 pages of results (often many more, for some packages) are shown, which have to be painfully scrolled through page-by-page to identify all the channels providing the specified package. This is slow and user-unfriendly.

Expected results:
One, more or (preferably) all of the following additional search options are available:

- The first search screen allows constraining the search to (a|one or more) specified product(s) and major release(s) (e.g. RHEL5 and/or RHEL6)

- After a result set is produced, the ability to filter the result set by (a|one or more) product(s) and major release(s) (e.g. RHEL5 and/or RHEL6)

- An option (checkbox) "Show only latest version of package for a given channel" is available when searching for the package


Additional information:
It is possible to acquire this information via the API, but use of the API should not be necessary for simple end-user queries such as this.
