hl7 fhir - Is it possible to make this query in ONE unique query: all observations for every patient with certain condition? -

we developing statistics module, based on fhir messaging, receives query making statistics grouping of patients attributes age, location, conditions, etc. . example, want create statistics observations in period grouping of patients in area condition.

is possible create 1 query rest api this: observations patients condition? have tried queries chained , compartment features, cannot it.

i appreciate help master of making fhir queries. if not, know can bring together different queries in _named query.

thanks in advance regards

this not presently possible.

we've done chaining :[find conditions subject refers has property]. needs reverse chaining: [find patients status refers has property]
