|
// normal range aggregation is that the from and to values can be expressed
|
|
// in Date Math expressions, and it is also possible to specify a
|
|
// date format by which the from and to response fields will be returned.
|
|
// Note that this aggregration includes the from value and excludes the to
|
|
// value for each range.
