• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22great britain) OR (xgreat britain))) OR (great britain)) %((((2f colonies) OR (4 colonies))) OR (et colonies)) %((2f administration) OR (trf administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22great britain) or (xgreat britain))) or (great britain)) %((((2f colonies) OR (4 colonies))) or (et colonies)) %((2f administration) or (trf administration))%22".
• Adding a wildcard symbol may retrieve word variants: %((((22great britain) or (xgreat britain))) or (great britain)) %((((2f colonies) OR (4 colonies))) or (et colonies)) %((2f administration) or (trf administration))%22*.
