Hi, I've found a difference between the cardinality setting of serviceType in the encounter to other resources that have this property (appointments, healthcare service, etc.), In the encounter is 0..1 only and not 0...*, Is it not mistake? we need to connect a few types to a single encounter, it is more problematic in the case the encounter is connected to an appointment with a few service types..

More in this issue, why there isn't search parameter for service-type like have in the Appointment ?  It can be added?
