In the application settings for a web map, I have enabled search by layer. My map only has two layers. I can add each layer to search by a particular field. However, when I try to add a single layer twice so that users can search by two different fields for a given layer, it says item has been successfully updated, but when refreshed, it only saves the search for one field. So I can't seem to add the same layer twice to search for two different fields.
