These results are all packages from the official Ubuntu repositories of the Ubuntu versions which are listed in the third column of the example rmadison results. Note that the results of rmadison also include results for Ubuntu 18.10 which is not officially released yet and Ubuntu 12.04 which is an End Of Life release.
If you can't remember the exact package name rmadison won't return any results, but this command will work:
firefox --new-tab https://packages.ubuntu.com/wireshar
The above command relies on fuzzy keyword search, so it also returns results that you don't want.
