Extension: CapabilityStatement Search Parameter Combination

Official URL: http://hl7.org/fhir/StructureDefinition/capabilitystatement-search-parameter-combination Version: 5.1.0
Standards status: Trial-use Maturity Level: 3 Computable Name: CSSearchParameterCombination
Other Identifiers: OID:2.16.840.1.113883.4.642.5.1044

This extension defines a possible search parameter combination by listing a set of search parameters and indicating whether they are required or optional.

  • If a search combination is specified, clients should expect that they must submit a search that meets one of the required combinations or the search will be unsuccessful.
  • If multiple search parameter combinations are specified, a client may pick between them, and supply the minimal required parameters for any of the combinations.
  • If no parameters in the set of search parameters are listed as required, then at least one of the listed optional parameters must be present. This shorthand method is the same as repeating the entire extension for each combination of optional and required search parameters.
