custom Subscriber searchparameter for resource Coverage fails :(((

[algusen]

We added a new custom searchparameter - subscriber:

INSERT INTO searchparameter(id,version_id, resource_type, resource, created_at, updated_at)
VALUES ('Coverage-subscriber','Coverage-subscriber','SearchParameter'
,'{
"id": "Coverage-subscriber",
"url": "http://hl7.org/fhir/SearchParameter/Coverage-subscriber",
"base": "Coverage",
"code": "subscriber",
"date": "2016-05-11T13:22:00+00:00",
"name": "subscriber",
"type": "reference",
"xpath": "f:Coverage/f:subscriber",
"target": ["Patient"],
"contact": [{
"telecom": [{
"value": "http://hl7.org/fhir",
"system": "other"
}]
},
{
"telecom": [{
"value": "http://www.hl7.org/Special/committees/fiwg/index.cfm",
"system": "other"
}]
}],
"publisher": "Health Level Seven International (FHIR Infrastructure)",
"xpathUsage": "normal",
"description": "subscriber",
"resourceType": "SearchParameter"
}'::jsonb

,CURRENT_TIMESTAMP,CURRENT_TIMESTAMP);

But

SELECT fhir_search('{"resourceType": "Coverage", "queryString": "subscriber=02255d1f-548c-4b04-9ac2-7c97d3efad1a"}');

or

SELECT fhir_index_parameter('{"resourceType": "Coverage", "name": "subscriber"}');

fail with the following error:

[Err] ERROR: Error: MetaIndex: Element [["Coverage","subscriber"]] -> Patient.subscriber not found
DETAIL: plv8_init() LINE 3641: throw new Error("MetaIndex: Element [" + (JSON.stringify(path)) + "] -

What's wrong with the subscriber parameter??

Looks like there is no Coverage.subscriber element in fhirbase FHIR metadata. I think we should update it. Do you use STU3? To quick fix just update Coverage StructureDefinition with new one.

[Semalexa]

Coverage.subscriber was in FHIR v1.0.2. In FHIR v1.4.0 this field was removed, now there are Coverage.planholder[x] (planholderIdentifier, planholderReference) and beneficiary[x] (beneficiaryIdentifier, beneficiaryReference).
So the search should be like [base]/fhir/Coverage?beneficiaryreference=Patient/<id>

Which release of fhirbase to take for HL7+FHIR DSTU2 (v1.0.2-7202) standard?

We work with standard HL7+FHIR DSTU2 (v1.0.2-7202) (http://hl7.org/fhir/), so which release of fhirbase should I take for my new database to follow this standard? Just now I took simply the last one (v.1.4.0.0), is it correct?
