• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"The expert's voice in .NET\") OR (\"The emperor's voice in .NET\"))".
• Removing quotes may allow a broader search: (( The expert's voice in .NET ) OR ( The emperor's voice in .NET )).
• Adding a wildcard symbol may retrieve word variants: (("The expert's voice in .NET") OR ("The emperor's voice in .NET"))*.
