     *   * `deployment_type.enum_values.values.id` - The allowed value id of the
     *   deployment_type attribute associated with the Deployment. Allowed

     *   * `deployment_type.enum_values.values.display_name` - The allowed value
     *   display name of the deployment_type attribute associated with the
     *   Deployment. Allowed comparison operators: `:`.
     *   * `slo.string_values.values` -The allowed string value of the slo
     *   attribute associated with the deployment. Allowed comparison
     *   operators: `:`.
     *   * `environment.enum_values.values.id` - The allowed value id of the

     *   allowed value id of the user defined enum attribute associated with the
     *   Resource. Allowed comparison operator is `:`. Here
     *   user-defined-attribute-enum-id is a placeholder that can be replaced with

     *   attributes/user-defined-attribute-id.enum_values.values.display_name`
     *   - The allowed value display name of the user defined enum attribute
     *   associated with the Resource. Allowed comparison operator is `:`. Here
     *   user-defined-attribute-enum-display-name is a placeholder that can be
     *   replaced with any user defined enum attribute enum name.
     *   * `attributes.projects/test-project-id/locations/test-location-id/
     *   attributes/user-defined-attribute-id.string_values.values` - The
     *   allowed value of the user defined string attribute associated with the

     *   any user defined JSON attribute name.
     * A filter function is also supported in the filter string. The filter
     * function is `id(name)`. The `id(name)` function returns the id of the

     * operator but not both of them together i.e. only one of the `AND` or `OR`
     * operator can be used throughout the filter string and both the operators
     * cannot be used together. No other logical operators are supported. At most
     * three filter fields are allowed in the filter string and if provided
     * more than that then `INVALID_ARGUMENT` error is returned by the API.
