• The words AND, OR and NOT may confuse the search; try adding quotes: "%22imf ((staff country) OR (estate country)) report%((gb country) or (((3d country) or (old country)))) report%22".
• Adding a wildcard symbol may retrieve word variants: %22imf ((staff country) OR (estate country)) report%((gb country) or (((3d country) or (old country)))) report%22*.
