SearchWidget Class
The Search widget provides a way to perform search operations on locator service(s), map/feature service feature
layer(s), SceneLayers with an associated feature layer, BuildingComponentSublayer with an associated feature layer,
GeoJSONLayer, CSVLayer, OGCFeatureLayer, and/or table(s). If using a locator with a geocoding service, the
findAddressCandidates operation is used, whereas queries are used on feature layers.
