Full Description

**Logical id of this artifact**  
NOTE: This SearchParameter is defined only to document Server and Client expectations. Its definition is derived from the standard FHIR SearchParameter and it uses the [Conformance expectation extension](http://hl7.org/fhir/StructureDefinition/capabilitystatement-expectation) to define additional expectations for the following SearchParameter elements:
- `multipleAnd`
- `multipleOr`
- `comparator`
- `modifier`
- `chain`

It **SHALL NOT** be used as a search parameter for search. Servers and Clients **SHOULD** use the standard FHIR SearchParameter.
