Code.Google is a website that allows users to maintain Code. Not a lot of recruiters try to source there. The reason is simple they do not know how. Well to do this without worry you need go no further than into your bag of tricks and pull out an old tried and true tool, a simple search with some extras
So to source within Code.Google you simply need to use a skill known as xraying, like the one below. Now the interesting thing is this will actually be a Github results once you open the pages.
If you run the strings above in google you will get the results below.
