Add search parameter

The code about search parameters can be found in models\FHIR\queryBuild.js and models\FHIR\searchParameterQueryHandler.js files.

• queryBuild.js: get single MongoDB query object from data type.
• searchParameterQueryHandler.js: using queryBuild.js and get fully MongoDB query object from HTTP query param.

Some search parameters from generator will got missing or incorrect. You can fix by using methods in models\FHIR\searchParameterQueryHandler.js.

Example: Bundle.composition

In some use cases, you may want to search patient/{id} in entry.resource.subject.reference of bundle resource.

• The example URL:

http://localhost:8080/fhir/Bundle?composition.patient=Patient/123

If you wanna support this parameter, you can add code in api/FHIR/Bundle/BundleParametersHandler.js.

//#region composition.patient
// search parameter name: "composition.patient"
// field in resource: "entry.resource.subject.reference"
// type: reference
paramsSearchFields["composition.patient"]= ["entry.resource.subject.reference"];
paramsSearch["composition.patient"] = (query) => {
    try {
        queryHandler.getReferenceQuery(query, paramsSearchFields, "composition.patient");
    } catch (e) {
        console.error(e);
        throw e;
    }
};
