|" ": tells the database you’re interested in a specific phrase, narrows search results||"synthetic environments"|

The "No Results" page in Library Search happens when the search terms do not match any items in the local discovery index.
The "No Results" page suggests trying the left side filter called, "Add results beyond your library's collection."
When you choose this filter then Library Search expands its discovery index to include citations which we may not have access to.
A primary benefit to seeing the additional citations is that those citations are then available to be requested.
