With the CARIN IG loaded, a search for ExplanationOfBenefit by service-date is not working as expected.

Environment

To Reproduce
Steps to reproduce the behavior:

1. ensure the fhir-ig-carin-bb jar is in userlib and start the server
2. upload an ExplanationOfBenefit resource with a ExplanationOfBenefit.item.servicedDate
3. perform a search with [base]/ExplanationOfBenefit?service-date=YOURDATE

note it comes back empty

Additional context
There is a corresponding upstream issue at https://jira.hl7.org/browse/FHIR-30443

[prb112]

I loaded the spec examples, and executed a test against https://localhost:9443/fhir-server/api/v4/ExplanationOfBenefit?service-date=ge2019

I confirmed the example was found using the search-parameter that is updated.
