In esri's 3.x or 4.x version, how can I search a feature layer by a field that has duplicate records?  For example, I want to search my feature layer with employers.  If I type "Mcdonalds", I get a list full of suggestions that all say "Mcdonalds" like this:

What I want to show in the suggestions is something like this:

Mcdonalds - address1

Mcdonalds - address2

Mcdonalds - address3

Mcdonalds - address4

Here is a section of my code for initializing the search widget.  I am specifying the "displayName" option: 

var sources = [{
   featureLayer: new FeatureLayer({ url: url, popupTemplate: popupTemplate }),
   searchFields: layer.search.searchFields,
   displayField: layer.search.displayField,
   name: layer.search.title || layer.title,
   outFields: layer.search.outFields,
   placeholder: layer.search.placeHolder
}]
var search = new Search({
viewModel: {
view: app.mapView,
maxSuggestions: 4
},
sources: sources
},'divID');

I am pretty sure there is no way in the api to do this.  Has anyone done this in their project or have any recommendations?

Jack,

  You need to look at the suggestionTemplate property of the sources object. Here is an example:

{
     featureLayer: new FeatureLayer("http://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/US_Senators/FeatureServer/0"),
    searchFields: ["Name", "Party"],
    suggestionTemplate: "${Name}, Party: ${Party}",
    exactMatch: false,
    outFields: ["*"],
    name: "Senators",
    labelSymbol: textSymbol,
    placeholder: "Senator name",
    maxResults: 6,
    maxSuggestions: 6,
    enableSuggestions: true,
    minCharacters: 0,
    localSearchOptions: {distance: 5000},
   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Robert,

Thank you so much!  This worked perfectly!  Not sure how I missed this in the documentation.  You always seem to be the one answering questions here on GeoNet.  I greatly appreciate it!

Yes, same here... I kept trying to figure out the displayField parameter. The above worked great except that I found no use for the $'s. If you have features with a Name and Number attribute, this worked:

suggestionTemplate: "Name: {NAME}, Number: {NUMBER}",
