title: CKAN Spatial Search Widget not returning any result
body: <p>I've added Spatial Search Widget to CKAN setup. I can see the map on the dataset listing page and on the left panel of the individual dataset page. However, when I 'search' using the map on the listing page, it returned no result and the map on individual page does show the GEO location. You can see from the screenshots. Any idea why this happens?</p>
