### Question:
VehicleSearchServiceImpl implements VehicleSearchService { @Override public List<VehicleStatus> search(List<VehicleStatus> vehicleStatusRecords, Map<VehicleSearchParameters, String> searchParameters) { List<VehicleStatus> matchingRecords = new ArrayList<VehicleStatus>(); List<Filter<VehicleStatus>> filters = buildFilters(searchParameters); if(filters.isEmpty()) { matchingRecords.addAll(vehicleStatusRecords); } else { for(VehicleStatus vehicleStatus : vehicleStatusRecords) { boolean matches = applyFilters(vehicleStatus, filters); if(matches) { matchingRecords.add(vehicleStatus); } } } return matchingRecords; }  @Override List<VehicleStatus> search(List<VehicleStatus> vehicleStatusRecords,
			Map<VehicleSearchParameters, String> searchParameters); @Override List<VehicleStatus> searchVehiclesInEmergency(
			List<VehicleStatus> vehicleStatusRecords); @Override List<VehicleStatus> searchVehiclesInRevenueService(
			List<VehicleStatus> vehicleStatusRecords); @Override List<VehicleStatus> searchVehiclesTracked(int minutes, List<VehicleStatus> vehicleStatusRecords); @Override List<VehicleStatus> searchActiveRuns();  }### Answer:
