Of course you can work around it if you know how to google, but Java and Python are much easier to search. If you look up "java books" or "python books" you get links about programming language books, not about coffee/Indonesia/serpents.
That's because of adoption and less sites linking and discussing go topics at the moment.
I think if you could Google when Python was in it's infancy, you would get 100s results for pythons (the snakes) before you saw Python pages...
Google search algorithm is not so naive as to understand "go" as a generic token only. It can tell from context which pages are related to "go" the language and which merely use the verb "go". The reverse is how old engines used to work, Altavista and co, where you had tons of irrelevant exact matches.
