Base expression in studies over API

Where can I find documentation on how to use Basic Expression when requesting studies (custom, advanced) using the API?

All I can find is this
http://partners.cqg.com/sites/default/files/docs/CQGAPI_4.0R/webframe.html#CQG~CQGAdvancedStudyRequest~BaseExpression.html

    Hi, rosor,
    The "Base Expression" is the instrument symbol. You can use the root symbol, or the full symbol if you want something other than the top step contract. For the current top step emini S&P, you could use just "EP." For the March 2017 contract you would use "EPH7."
    Have you checked out the sample code found here? It's a great way to quickly play with CQG-specific operations.
