Hapi Fhir query with AND / OR with map - hapi-fhir

Question

Using Hapi Fhir, I try to write a query to use a map to pass in where condition, as follow:
Map<String, List<IQueryParameterType>> hmParameter = criteria.getMapForWhere();
Bundle bundle = fhirClientR4Configuration.clientFhihrR4().search().forResource(ServiceRequest.class)
.where(hmParameter).returnBundle(Bundle.class).execute();
My criteria object has a method getMapForWhere() where I populate this map with information inside my wrapper front end object as follow:
public Map<String, List<IQueryParameterType>> getMapForWhere() {
Map<String, List<IQueryParameterType>> hmOut = new HashMap<String, List<IQueryParameterType>>();
// Adding STATUS
if (this.status != null && !this.status.equals("")) {
StringParam sp = new StringParam();
sp.setValue(this.status);
List<IQueryParameterType> lst = new ArrayList<IQueryParameterType>();
lst.add(sp);
hmOut.put(ServiceRequest.SP_STATUS, lst);
}
// Adding INTENT
if (this.intent != null && !this.intent.equals("")) {
StringParam sp = new StringParam();
sp.setValue(this.intent);
List<IQueryParameterType> lst = new ArrayList<IQueryParameterType>();
lst.add(sp);
hmOut.put(ServiceRequest.SP_INTENT, lst);
}
return hmOut;
}
This code works fine when I want to wirte a query with all AND.
But if I want to add another condition as follow:
List<IQueryParameterOr> lstOr = new ArrayList<IQueryParameterOr>();
StringOrListParam lstServices = new StringOrListParam();
StringParam sp = new StringParam();
StringParam sg = new StringParam();
sp.setValue(MEDICAL_SERVICE_PAI);
sg.setValue(SOCIAL_SERVICE_PAI);
lstServices.addOr(sp);
lstServices.addOr(sg);
lstOr.add(lstServices);
hmOut.put(ServiceRequest.SP_CATEGORY, lstOr);
Obviously hmOut goes in error because definition of that map is different. But I don't know how to convert IParameterOr with IParameterType.
