+  <pre>Searches for Groups.
+
+Args:
+  pageSize: integer, The default page size is 200 (max 1000) for the BASIC view, and 50
+(max 500) for the FULL view.
+  pageToken: string, The next_page_token value returned from a previous search request, if any.
+  query: string, Query string for performing search on groups.
+Users can search on namespace and label attributes of groups.
+EXACT match ('=') is supported on namespace, and CONTAINS match (':') is
+supported on labels. This is a `required` field.

+sensitive.
+An example query would be:
+"namespace=<namespace_value> AND labels:<labels_value>".
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
