LayerSearchSource

The following properties define a Layer-based source whose features may be searched by a Search widget instance.

For string field searches, there is no leading wildcard. This effectively makes exactMatch true, which will remove unnecessary search results and suggestions.

Layers created from client-side graphics are not supported.

Property Details

autoNavigate Inherited Property autoNavigate Boolean Inherited from SearchSource

Indicates whether to automatically navigate to the selected result once selected.

Default Value:true

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

displayField Property displayField String

The results are displayed using this field. Defaults to the layer's displayField or the first string field.

exactMatch Property exactMatch Boolean

Indicates to only return results that match the search value exactly. This property only applies to string field searches. exactMatch is always true when searching fields of type number.

Properties: where String

optional
The where clause specified for filtering suggests or search results.

geometry Geometry

optional
The filter geometry for suggests or search results. Extent is the only supported geometry when working with locator sources. See Find Address Candidates for additional information.

Example

const theExtent = new Extent({
  xmin: 11376463,
  ymin: -5163501,
  xmax: 18890529,
  ymax: -662888,
  spatialReference: {
    wkid: 3857
  }
});

const searchExtent = {
  geometry: theExtent,
  where: "TERRITORY = 'Northern Territory'"
};

const sources = [{
  layer: featureLayerTourism,
  placeholder: "Darwin",
  maxResults: 5,
  searchFields: ["POI"],
  displayField: "POI",

  filter: searchExtent
}];

const searchWidget = new Search({
  view: view,
  sources: sources
});

getResults Inherited Property getResults GetResultsHandler Inherited from SearchSource

layer Property layer Layer

The layer queried in the search. This is required. The layer can be a map/feature service feature layer(s), SceneLayers with an associated feature layer, BuildingComponentSublayer with an associated feature layer, GeoJSONLayer, CSVLayer or OGCFeatureLayer. See the SceneLayer Guide page on how to publish SceneLayers with associated feature layers.

The geometry type of the layer affects the behavior when a result is found. If the layer type is Point, the view will pan, but not zoom, to the result. If the layer type is Polygon or Polyline, the view will pan and zoom to the result.

Feature layers created from client-side graphics are not supported.

maxResults Inherited Property maxResults Number Inherited from SearchSource

Indicates the maximum number of search results to return.

Default Value:6

popupTemplate Inherited Property popupTemplate PopupTemplate Inherited from SearchSource

The popup template used to display search results. If no popup is needed, set the source's popupTemplate to null.

This property should be set in instances where there is no existing PopupTemplate configured. For example, feature sources will default to any existing popupTemplate configured on the layer.

prefix Inherited Property prefix String Inherited from SearchSource

Specify this to prefix the user's input of the search text.

resultGraphicEnabled Inherited Property resultGraphicEnabled Boolean Inherited from SearchSource

Indicates whether to show a graphic on the map for the selected source using the resultSymbol.

searchFields Property searchFields String[]

An array of string values representing the names of fields in the feature layer to search.

searchTemplate Property searchTemplate String

A template string used to display multiple fields in a defined order when results are displayed.

Example

LayerSearchSource.searchTemplate = "{County}, {State}";

suffix Inherited Property suffix String Inherited from SearchSource

Specify this to add a suffix to the user's input for the search value.

suggestionsEnabled Inherited Property suggestionsEnabled Boolean Inherited from SearchSource

Indicates whether to display suggestions as the user enters input text in the widget.
