Chained parameter

I need to define chained search parameters ; for instance, I would like to search within Slot resource using
I can create a SearchParameter resource derived from with base=Slot, target=Patient and chain=identifier. But where do I specify the element “actor” ?
Thanks !

chain would actually be actor.identifier, though the documentation should be updated to be clear this is supported. Can you submit a change request? (Use the “propose a change” link at the bottom of any page in the spec.

Thank you lloyd ! Of course, I can submit change requests (I need to define ~20 new chained parameters, so I will submit several change requests…)

The change requests wouldn’t be to defined chained search parameters - those you’ll have to do yourself. The change request would be to clarify the mechanism for defining deep chaining (more than one level).
