Use FHIR searchsearch interaction can be performed using either a GET
or POST request. For searches that involve personally identifiable information (PII) or protected health information (PHI), it's
recommended to use POST requests, as PII and PHI is added as part of the request
body and is encrypted in transit.
Note
The FHIR search interaction described in this chapter is built in conformance
to the HL7 FHIR R4 standard for health care data exchange. Because it is a representation of
a HL7 FHIR service, it is not offered through AWS CLI and AWS SDKs. For more information,
see search
HealthLake supports a subset of FHIR R4 search parameters. For more information, see FHIR R4 search parameters for HealthLake.
