Yes, but the OP was interested in what the ">>" line did, so he likely searched for something like "$? >> 8" -- and the results for that are not nearly as useful because Google doesn't treat that as a phrase. So while the docs do indeed clearly answer the question, the most obvious search at first glance will not take you to the docs. In other words, "The docs answers your question" would have sufficed -- no nead to use "clearly" and the negative connotations that it implies.
