-- | Sorts list results by a certain order. By default, results are returned
-- in alphanumerical order based on the resource name. You can also sort
-- results in descending order based on the creation timestamp using
-- orderBy=\"creationTimestamp desc\". This sorts results based on the
-- creationTimestamp field in reverse chronological order (newest result
-- first). Use this to sort resources like operations so that the newest
-- operation is returned first. Currently, only sorting by name or
-- creationTimestamp desc is supported.

-- | Sets a filter expression for filtering listed resources, in the form
-- filter={expression}. Your {expression} must be in the format: field_name
-- comparison_string literal_string. The field_name is the name of the
-- field you want to compare. Only atomic field types are supported
-- (string, number, boolean). The comparison_string must be either eq
-- (equals) or ne (not equals). The literal_string is the string value to
-- filter to. The literal value must be valid for the type of field you are
-- filtering by (string, number, boolean). For string fields, the literal
-- value is interpreted as a regular expression using RE2 syntax. The
-- literal value must match the entire field. For example, to filter for
-- instances that do not have a name of example-instance, you would use
-- filter=name ne example-instance. You can filter on nested fields. For
-- example, you could filter on instances that have set the
-- scheduling.automaticRestart field to true. Use filtering on nested
-- fields to take advantage of labels to organize and search for results
-- based on label values. To filter on multiple expressions, provide each
-- separate expression within parentheses. For example,
-- (scheduling.automaticRestart eq true) (zone eq us-central1-f). Multiple
-- expressions are treated as AND expressions, meaning that resources must
-- match all expressions to pass the filters.
