Describe the bug Given a Patient resource https://my-server/fhir/Patient/1234 and compartment Patient/1234 When I search for RelatedPerson GET https://my-server/fhir/RelatedPerson?patient=https://my-server/fhir/Patient/1234 Then the server responds with 403 Unauthorized

(Note: URL encoding is omitted for readability)

However, When I search for RelatedPerson GET https://my-server/fhir/RelatedPerson?patient=Patient/1234 Then the server responds with all RelatedPersons with patient=https://my-server/fhir/Patient/1234

To Reproduce Steps to reproduce the behavior:

• create Patient
• create RelatedPerson with above patient
• Extend SearchNarrowingInterceptor.java and add compartment return new AuthorizedList().addCompartment("...")
• perform search ad described in the previous section

Expected behavior GET https://my-server/fhir/RelatedPerson?patient=https://my-server/fhir/Patient/1234 and GET https://my-server/fhir/RelatedPerson?patient=Patient/1234 should be equivalent,

Environment (please complete the following information):

• HAPI FHIR Version : 5.6.1

Additional context Worked in 5.5.3

@tadgh - any chance you will have a look at this?

If I'm being honest I didn't even know you could do that search by absolute patient reference. Since this looks like a regression I'd be happy to fix it if we can find out what regressed it.

If you can get a failing unit test I'd be happy to git bisect the repository to find out what caused the change and why. Sadly I don't have the time to dedicate to writing one myself at the moment.
