Just wondering if I'm missing something simple here...
If you upload a zip file of multiple SHP files or a geodatabase with mutliple feature classes to Portal, the resulting published feature service contains sublayers for the various feature classes. This is great for organizing multiple datasets under a single named feature service, however, it appears that by default you cannot search for the sublayer names? Is there a way to search for these sublayer names or am I missing something? Is adding all the sublayer names as tags the only way to manage this? I sure hope the latter is not the solution...
