• If you are trying to use Boolean operators, they must be ALL CAPS: %((saving banks) OR (savings bank)) %((((2f history) OR (ref history))) OR (((imf history) OR (bief history))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((saving banks) OR (savings bank)) %((((2f history) or (ref history))) or (((imf history) or (bief history))))%22".
• Adding a wildcard symbol may retrieve word variants: %((saving banks) OR (savings bank)) %((((2f history) or (ref history))) or (((imf history) or (bief history))))%22*.
