I see that https://codesearch.wmflabs.org/operations/ does not support search in rOPUP Wikimedia Puppet, nor in the Everything tab either. I feel being able to look for code or strings in the operations/puppet.git repo would be very useful. Please consider adding support for that repository. Thank you.
puppet is not included because its default branch is named production and hound hardcodes master. Of course, this is a super silly reason that I think we can just workaround instead of waiting for an upstream fix...
After a bit of searching, I learned about git-symbolic-ref which allows you to alias git refs. So I was able to locally alias production -> master for the purposes of hound, and it seemed to work fine in my local testing.
