How to restrict Search to a certain extent?

Question

I am replacing my GeoCoder  Widget with Search Widget. In GeoCoder i can restrict my search in a certain area by doing this:
arcgisGeocoder: true,
 arcgisGeocoder: {
       placeholer: "Enter a US street address",
       searchExtent: new esri.geometry.Extent({
       xmin: -8631362.9367,
       ymin: 4655884.590300001,
       xmax: -8532954.2208,
       ymax: 4772527.9208,
       spatialReference: { "wkid": 102100 }
 }),
 url: "http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer"
 }

As i was looking into the search widget in JS 4.3, i could not find equivalent  options. Any ideas of how to set such options in Search Widget?

Hemming,

You set the searchExtent on the Search widgets source array:
