 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.
