Or discussion is about how well can be package searched in particular search services, how the results are organized and readable, ... and you are arguing with package distributed somewhere else. You must be demagogue.
Neither you can find libdvdcss or w32codecs in Ubuntu repositories or download.ubuntu.com. Just because they were quarantined at medibuntu.org.
The fact that you now want to back-track and direct me to a different service than http://software.opensuse.org/ to provide me with functionality you wanted to slag off https://launchpad.net/ubuntu/+ppas for lacking suggests to me that being unable to simply "find some exact package for exact Ubuntu version using this tool?" to quote you is possibly also a same type of failure of http://software.opensuse.org/
I wanted you to show:
find some exact package for exact Ubuntu version using this tool?
Everybody understand this, for idiot like you, I add obvious condition:
Package must exist in PPA
because, you can not show searching capabilities, where you search something non-existent.
When you search package of your choice on PPA site, search engine will not give you results of packages found, only a big mess of some repositories.
When you search download.opensuse.org, search engine will give you results of packages, versions, repositories, even distributions a distribution versions if you search among all distributions and such packages exist in buildservice. That is why is download.opensuse.org much better tool, because it gives you COMPLETE RESULT, not some partial information like PPA search.
And if I was looking for say "kdenlive_0.7.8-0ubuntu0~sunab~maverick1_amd64.deb" I could simply type it into "teh google" and get a result.
