Are GitHub sources explored by search engines?

Question

Will Google and other search engines index my source code if I save them to GitHub?

Answer 1

Yes, search example site:github.com on Google.

Answer 2

Access to the source code is not denied. GitHub Robot exclusion policy , so I assume that yes, your source code will be indexed.

On the other hand, my attempts to find my own source code on Google do not give any results, so I could be wrong.
