find all HealthcareService resources for a given Practitioner - fhir search

Question

I'm struggling a bit with reverse chaining in fhir search.

I can find all PractitionerRole resources for a given Practitioner with:

[base]/PractitionerRole?practitioner:Practitioner:id=100

How do I combine chaning and reverse chaining to find all HealthcareService resources for a given Practitioner? I tried the below and some variations of it.

[base]/HealthcareService?_has:PractitionerRole:practitioner:Practitioner:id=100

Answer 1

I would use: [base]/PractitionerRole?practitioner=100&_include=PractitionerRole.service

It's more likely to be supported, and would also give you the roles in which the Practitioner is associated with the service.
