Search

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.

By default, the Search widget uses the ArcGIS World Geocoding Service via this URL: https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer. If a global apiKey is present, the Search widget uses this URL: https://geocode-api.arcgis.com/arcgis/rest/services/World/GeocodeServer. If an apiKey is present on the LocatorSearchSource, then the Search widget uses the URL defined by the LocatorSearchSource.url property.

The Search widget sets the view on the Search result. The level of detail (LOD) at the center of the view depends on the data source, with higher quality data sources returning extents closer to the feature obtained from the search. To manually define the scale of the view at the Search result, use the zoomScale property of the LocatorSearchSource or LayerSearchSource.

Search widget results are typically sorted according to their relevance to the search and their relative importance. However, when the scale of the MapView or SceneView is less than or equal to 300,000, the operations support prioritization of candidates based on their distance from a specified point (the center of the view) by passing in the location parameter. Features closest to the input location show up higher in the list of results. This behavior can be changed by using the localSearchDisabled property.

You can use the view's DefaultUI to add widgets to the view's user interface via the ui property on the view. See the example below.
