Clear Global Search results?

I have a workflow that clears all highlights and selections from the map and deactivates the results views, however it does not clear the results returned from a Global Search. In the workflow I am using the commands "ClearSearch", "CancelSearch", "ClearHightlights", "ClearSelection", "DeactivateView" (ResultListView), "DeactivateView" (ResultTableView). If there are additional commands to deal with the Global Search results, I have not been able to find them. The item remains  highlighted and the results view does not close. Any hints out there?
