Of course, Go itself is completely unsearchable, so you always have to search for Golang, which means that thee mut be hundreds of pages that get missed.
And "C" or "D" are searchable? Or "Java" (island, coffee) or "C#" (musical scale)? Or "Basic" (fundamental)? Or "Python" (snake) or "Ruby" (gemstone)? Or "Lisp" (speech impediment)? Or "Pascal" (French mathematician, SI unit and general given name)? Or "Smalltalk" (informal conversation)? Or "Logo" (emblem)? Or "Lua" (Portuguese word for moon)? ...
In my humble opinion, in the vast majority of cases, yes. Because " C ", " D ", " C# " should be easier for search engines to disambiguate (at least working with Lucene, it is, and I imagine Google etc are similar-ish).
As for Java, Python the context in the page likely to point to its intended audience (and it helps they have been around for ages etc). Otoh, " go " is likely to be used in a lot of literature, including other programming related texts.
Try searching for something with clojure, and then try go -- the quality of results is usually substantially different, and my unsubstantiated hunch is that not all of it has to do with lack of go-related content.
I would think that the search algorithms are smart enough to conflate references to go in an article about programming with golang as a search query. I am not a google engineer but I do know that they have very good "did you mean" analysis on search queries.
