As far I know many developers using Go uses "golang" phrase to receive more precise results in search engine, but Google Trends denies such usage of this "trick". I made comparison  between the "Go", "Golang", "Elixir", "C#" and I felt pretty amazed that Go phrase is popular the same as C# - I would like to, but I don't think that can be truth. I really suggest to stop using Google Trends as a "representable source" which i.e. programming language is better known (sadly this practice is very popular, even during lectures at colleges/universities or in various publications).
