I have "shared" the ESRI basemaps with a private group which contains other basemaps from my organization, yet I can only see my basemaps when I query the group from javascript. If I click on the group in ArcGIS Online then I see the ESRI basemaps and my private basemaps. However, if I perform a javascript query against my private group using the group ID then I only get our basemaps and not the ESRI basemaps. As a test, I want to see if I could return only esri basemaps with this query: q: "title: \"ArcGIS Online Basemaps\" AND owner:esri" but no results are returned. How can I return the results of our non-public basemaps and esri basemaps together in one query?
