#### Order By

Type: array of string Default: []

An array of field names describing the manner in which query results should be ordered. The field names may also have one of more of the following special prefixes: `-` (reverse sort direction), `nulls_first:` (place any null values at the head of the results list), `nulls_last:` (place any null values at the tail of the results list).

No Additional Items

##### Each item of this array must be:

Type: string
Example:

    [
        "size",
        "-devname",
        "nulls_first:-expiretime"
    ]

##
