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