I am using my owned prepared locator Geocode service (http://maps.dhalahore.org/ArcGIS/rest/services/DHAMAP/AddressLocator/GeocodeServer) in Geocode online (arcgis-appstudio-samples-master).

Working perfect on Reverse Geocoding but giving Error (Unable to complete operation. No Address Found) when i search any address in search box.

Here code:

Hi there,

There are couple of issues here, directly related to your Geocoding service.

1) Your geocoding service is based on server 10.0 and hence only supports FindAddressCandidates. Therefore you should be using
 locator.geocode() method to perform Geocoding. This method calls the FindAddressCandidates operation

2) Based on your service address field. It currently takes Single Address labelled as "SingleKey". Hence you should only use that as your Address field parameter.

I have added these suggestions in your code and pasted below for your reference.

I hope this helps.

Thank you.

I am very Grateful Nakul Manocha.

It's working perfect.

One question please "On performing search it's find all  addresses (E.g When I search 5 G 82 ,it's highlight 5 G 82,5 G 8/2 and 5 J 82) but I need when i write specific address it's only find that particular address.

It would be greatly appreciated.

 

Cheers,

If you want only one address then you check for the score condition within the results and don't include if the score is not 100. I see based on your Geocode service I am getting lots of results with score >90. Hence I would recommend (

result.score <100) then it will include only one record.

http://maps.dhalahore.org/ArcGIS/rest/services/DHAMAP/AddressLocator/GeocodeServer/findAddressCandid... 

else {
                    for (var i = 0; i < geocodeResults.length; i++) {
                        var result = geocodeResults[i];
                        if (result.score <100)
                            return;
                        var graphic = locationGraphicGeocode.clone()
                        graphic.geometry = result.location;
                        graphicsLayerGeocode.addGraphic(graphic);
                    }

Hope this helps,

I am very Grateful Nakul Manocha.

It's great idea.

 I will putt condition on my matching score based on my Geocode Service.

I will replay you after putting condition..

Again I am very thankful to you.

Very Grateful Nakul Manocha.

 

 I  putt condition

if (result.score <100)
return;

I working perfect and find only one address but it does not Zoom to that particular address.

Please see the screen shot.

 

Highlight Adress But does not Zoom

It would be greatly appreciated.

That is expected as the single point geometry doesn't have an extent ( as min x,y and max x,y has same values). What you would have to do is to create a virtual extent around the point geometry and then zoom to that extent. 

Another way is to create a buffer geometry (invisible- don't add it as graphic) around that point and then zoom to that buffer geometry.

I am very Grateful Nakul Manocha.

 

I create Locator with Minimum Match/Candidate Score 100.

Now,it's working perfect and find only one address and also Zoom to that particular address.

Again I am very thankful to you.
