How can I search for a commit message on GitHub?

Question

Not in a Git repository, but rather in GitHub specifically - how do I search just the commit messages of a specific repository/branch?

Answer 1

As of 2017 it's a functionality included in GitHub itself.

The example search used by them is repo:torvalds/linux merge:false crypto policy
