-- 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
-- (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, filter=name ne
-- example-instance.
