Search Parameter Patterns

Search parameter definitions include a FHIRPath expression that specifies how to extract values from resources. The library translates these expressions directly into native Kotlin extractFrom() functions during code generation.

Supported FHIRPath patterns

The following FHIRPath patterns produce a typed extractFrom() function:

Pattern Example
Simple property Patient.birthDate
Nested path Patient.address.city
List property Patient.identifier
Element cast (X.path as Type) (Patient.deceased as dateTime)
Element cast X.path.as(Type) Condition.onset.as(dateTime)
Element cast X.path.ofType(Type) Observation.value.ofType(Quantity)
Choice element (no cast) ChargeItem.occurrence
where(resolve() is Type) filter Account.subject.where(resolve() is Patient)
where(field='value') filter Patient.telecom.where(system='email')
Union of the patterns above Observation.value.ofType(dateTime) | Observation.value.ofType(Period)

Note

  • Choice elements without casting: Returns the sealed interface (e.g. ChargeItem.Occurrence) rather than the underlying value (e.g. DateTime, Period).
  • resolve() is Type filtering: Checks if 'Type/' is in the reference field (e.g. 'Patient/123'). Does not match URNs, contained resources, or references without a literal URL.
  • Unions: extractFrom() concatenates the results of each branch in expression order and eliminates duplicate values, matching FHIRPath's | operator. The value type is the branches' common type (e.g. CodeableConcept for AllergyIntolerance.code | AllergyIntolerance.reaction.substance) and widens to Any when the branches differ (e.g. dateTime | Period). Branches whose pattern is not supported are skipped; a parameter is unsupported only when none of its branches are. The parameters affected by skipped branches are listed below.

Partially extracted unions

For these parameters, extractFrom() extracts only the supported branches of the union. The expression metadata still carries the full expression, so the skipped branch can be evaluated with an external FHIRPath engine.

Version Parameter Extracted Skipped
R4, R4B Observation.value-string (Observation.value as string) (Observation.value as CodeableConcept).text
R5 CareTeam.name CareTeam.name CareTeam.extension('...careteam-alias').value
R5 Composition.section-text Composition.section.text Composition.section.section.text
R5 Device.serial-number Device.serialNumber Device.identifier.where(type='SNO')

Unsupported FHIRPath patterns

Where an expression pattern is not yet supported, its extractFrom() function throws a NotImplementedError and its return type defaults to Any. The generated object's unsupported property lists these parameters explicitly, and all excludes them so iterating all and invoking extractFrom() is safe. All metadata (name, type, expression, target) remains populated, allowing callers to evaluate the expression string with an external FHIRPath engine if needed.

The 87 search parameters with unsupported expressions across R4, R4B, and R5 fall into the following categories:

Empty FHIRPath expression

These parameters have no expression in the source SearchParameter-*.json, so there's nothing to translate. Most are FHIR-internal parameters (_content, _filter, _has, _list, _query, _text, _type) defined on Resource / DomainResource.

Composite search parameters with no component path

A composite search parameter combines two or more other parameters. For example, Observation's code-value-quantity combines code and value-quantity from the same Observation.component.

Other where(...) conditions

where(...) supports two conditions: where(<field>='<value>') and where(resolve() is <Type>). Anything else isn't supported. Example: QuestionnaireResponse's item-subject parameter uses where(hasExtension('<url>')) (R4) or where(extension('<url>').exists()) (R4B and R5) to check for an extension.
