-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.

   <pre>Stops a running instance, shutting it down cleanly, and allows you to restart the instance at a later time. Stopped instances do not incur per-minute, virtual machine usage charges while they are stopped, but any resources that the virtual machine is using, such as persistent disks and static IP addresses, will continue to be charged until they are deleted. For more information, see Stopping an instance.
