Topic: Change to SearchParameter.Base
Andrew Le Couteur Bisson (Nov 30 2017 at 09:12):
I am using the open-source Spark server with my own Sql back end and I have just upgraded the FHIR libraries to STU-3. One change that I do not understand is that SearchParameter.Base has changed from a ResourceType to IEnumerable<ResourceType?>. Could someone please explain the reason for this change? I can't see any SearchParameter definitions that reference more than one Resource and I am not even sure what that would mean. Also, is a null in the IEnumerable significant or does it just denote the absence of a value? i.e. is [Person, null] the same as [Person]?
Thanks,
Andy

The part on 'Common Search Parameters' on http://www.hl7.org/implement/standards/fhir/searchparameter-registry.html lists the search parameters that have multiple ResourceTypes.
