-  <pre>Retrieves the list of disks grouped by scope.
+  <pre>Retrieves an aggregated list of persistent disks.
 
 Args:
   project: string, Project ID for this request. (required)
-  maxResults: integer, Maximum count of results to be returned.
-  pageToken: string, Specifies a page token to use. Use this parameter if you want to list the next page of results. Set pageToken to the nextPageToken returned by a previous list request.
-  filter: string, 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.
+  maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests.
+  pageToken: string, Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.
+  filter: string, 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 (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.
+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, filter=name ne example-instance.
+For example, to filter for instances whose name is not equal to example-instance, you would use filter=name ne example-instance.
+
+Compute Engine Beta API Only: If you use 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. In particular, use filtering on nested fields to take advantage of instance labels to organize and filter 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.

+Compute Engine Beta API Only: If you use 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. In particular, use filtering on nested fields to take advantage of instance labels to organize and filter 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.
