• The words AND, OR and NOT may confuse the search; try adding quotes: "%saving banks %((((2f history) or (((imf history) or (brief history))))) or (((ref history) OR (bief history))))%22".
• Adding a wildcard symbol may retrieve word variants: %saving banks %((((2f history) or (((imf history) or (brief history))))) or (((ref history) OR (bief history))))%22*.
