Topic: Search parameter for Provenance
Camille Van Assel (Feb 20 2020 at 12:11):
Hello all,
I'm trying to create a search parameter for my provenance resource that would allow to search by agent type and reference.
My provenance agent look like that:
"agent": [
{
"type": {
"coding": [
{
"system": "http://terminology.hl7.org/CodeSystem/provenance-participant-type",
"code": "verifier",
"display": "Verifier"
}
]
},
"who": {
"reference": "Device/4704"
}
},
{
"type": {
"coding": [
{
"system": "http://terminology.hl7.org/CodeSystem/provenance-participant-type",
"code": "enterer",
"display": "Enterer"
}
]
},
"who": {
"reference": "Device/4705"
}
}
]
]
And I would like to be able to search something like /Provenance?agent-of-type=Device/4704$verifier&agent-of-type=Device/4705$enterer
So far I've just been able to search for the reference with:
"code": "agent-of-type",
"type": "reference",
"expression": "Provenance.agent.who"
Do you know if there is a way to combine it with the type of agent ?
Thanks for your help :)

I don't think you can do that.. but @Lloyd McKenzie would know, and I don't want to be told I was wrong for a third time this week... :-)

Yes, it'd be possible to define a composite search parameter that did that. In SearchParameter, you'd have to use SearchParameter.component - one for the type and one for the reference
