Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setQueryType([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
