Question:
I am trying to search some code in a branch in a GitHub repository.
However this indicates that I can only search the default branch.
Is there a way I can search code in non-default branch in my GitHub repository?
Answer:
Not from the GitHub web interface itself, as mentioned in “How can I search for a commit message on GitHub?“: only the default branch (generally master) is indexed.
Your best bet is to clone the repository, and there, search in all branches (with git log -S for instance).
