• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (xgreat britain)) %((p colonies) or (les colonies)) %((8 administration) OR (unis administration))%22".
• Adding a wildcard symbol may retrieve word variants: %((22great britain) or (xgreat britain)) %((p colonies) or (les colonies)) %((8 administration) OR (unis administration))%22*.
