Using Wildcards
To register or cancel a subscription for multiple event types, you may use a single wildcard character "*" at the end of the event type name.
If you use wildcards in the event type name, the following restrictions apply:
*Only those event types that your client has permission to subscribe to will be included in the subscription.
*Wildcards cannot be used with any event type within the scope of Broker::Trace or Broker::Activity.
*If a filter string is specified for the subscription, it may not contain any data fields. The filter string may contain envelop fields, however.
