Extra options are defined on a per-endpoint basis and are described in the documentation for the associated query method.

##

#### 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:

    [

#### Count

Type: boolean Default: false

##

#### Offset

Type: integer Default: 0

This specifies the beginning offset of the results array. When combined with the `limit` query-option it may be used to implement pagination of large results arrays. WARNING: some query methods provide volatile results and the onus is on the developer to understand whether pagination is appropriate for a particular query API method.

##

#### Limit

Type: integer Default: 0

This specifies the maximum number of results matching the specified `query-filters` to return. When combined wtih the `offset` query-option it may be used to implement pagination of large results arrays.
