\_result

By default, the search result is returned as a FHIR Bundle. You can change this behavior by setting _result=array and your search result will be returned as JSON array with resources, without the Bundle envelope:

GET /Patient?_result=array
# 200
- id: pt1
  resourceType: Patient
  name:
  - given: [Adam]
    family: Smith
- name:
  - given: [Andrew]
    family: John
  id: pt-1
  resourceType: Patient
