-- | 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. Compute Engine Beta API Only: When
-- filtering in the Beta API, you can also 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. The Beta API also supports filtering on multiple
-- expressions by providing 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.
