Patient :identifier Search Parameter Support
HDR FHIR supports patient identifier search for all resources.
The FHIR standard defines a modifier :identifier that can be used to limit the reference search parameter. In this manner, the system allows for searching by identifier rather than literal reference.
Example:
GET [base]/Consent?patient:identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608833630130
The example is a search for all Consent resources that reference a patient by a particular patient identifier. When the :identifier modifier is used, the search value works as a token search.
In this case, patient resource will not be created before, and it will be attached while persisting the resource.
Sample Message:
{
"resourceType": "Consent",
"id": "consent-example-basic1255",
"text": {
"status": "generated",
"div": "<div xmlns=\"http://www.w3.org/1999/xhtml\">\n\t\t\t<p>\n\tAuthorize Normal access for Treatment\n\t\t\t</p>\n\t\t\t<p>\n Patient "P. van de Heuvel" wishes to have all of the PHI collected at the Good Health Psychiatric Hospital \n available for normal treatment use.\n\t\t\t</p>\n\t\t</div>"
},

"provision": {
"period": {

}
}
}
When the above message is persisted, indexed patient references will generate an index in the HFJ_SPIDX_TOKEN table for the patient identifier.
Now you can search Consent resources that reference a patient by a patient identifier using the GET operation like below.
GET [base]/Consent?patient:identifier=http://test.com|12345
