After activating Staging the Search Widget Pages doesn't provide the correct search results for Private Content Pages due to the fact Guests users can't see them (instead the users will be seeing the content for the login page).
The goal of this story is to overcome this limitation from Private pages by having a warning that appears when Staging is activated.
When user is performing a search with Staging enabled
Then a warning shows "You are visualizing search results with Staging enabled. The search results won't produce the expected results. For accurate search results use the LIVE mode"
