Topic: Query for null
Richard Kavanagh (Oct 29 2021 at 09:21):
Is it possible to query for null in FHIR?
So if I wanted to query for an optional string element that was null or an identifier element that had no values etc...

We can use :missing modifier for creating such a query.
https://hl7.org/fhir/search.html#missing has more guidance

Thanks @Jeffy Mathew Jose - I've never noticed that before....
