How to search by FHIR extension ?

Lifen supports FHIR extension. As such, extensibility is a fundamental part of the design of FHIR specification. Every element in a resource can
have extension child elements to represent additional information that is not part of the basic definition of the resource. You can read more about extension here

Example of an extension :

{
    extension: [
        {
            "url": "http://lifen.fr/fhir/StructureDefinition/Resource/ExtensionX",
            "valueBoolean": true
        }
    ]
}

Search by extension in the FHIR search must respect the token param syntax fitting into one of the following schemas:

• [baseUrl]/[resource]?_extension=[url]|[value] : any resource with extension where the value of [url] matches the url property and the value of
  [value] matches the value property
• [baseUrl]/[resource]?_extension=[url]| : any resource with extension where the value of [url] matches the url property
• [baseUrl]/[resource]?_extension=[value] : any resource with extension where the value of [value] matches the value property
• [baseUrl]/[resource]?_extension=|[value] : any resource with extension where the value of [value] matches the value property
