When searching in ArcGIS Online or Portal for ArcGIS with the Gazetteer address locator style for a geocode service for a polygon layer, the map zooms to and places the pop-up for the polygon at the origin of the projection (0, 0). This behavior is seen with the Gazetteer address locator style for geocode services published to ArcGIS for Server 10.3.1.
Duplicate of BUG-000083913 : This bug was addressed but will require you to create the locator again from scratch using 10.3.1.
解决办法
Use the Single Field address locator style instead of the Gazetteer address locator style which returns the point geometry for the polygon centroid. The same issue is not encountered as seen with the Gazetteer address locator style in ArcGIS Online.
