I wanted to know which pattern provides [WayBack] etckeeper which is in the [WayBack] openSUSE Software package etckeeper.
It seems no built-in search query can do that, so I built one my own.
Since the result takes quite a while to produce, the output is a pattern.txt that you can manually search.
This is the command:
zypper search -t pattern | grep "|" | tail -n +2 | perl -pe 's/^.*? \| //' | perl -pe 's/ *\| .*$//' | xargs -I {} sh -c "zypper info -t pattern {}" > patterns.txt
The content is like this (the 2017 date shows I wrote this a long time ago):
