• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %((2f colonies) or (((((et colonies) OR (les colonies))) or (_ colonies)))) %((2f administration) or (trade administration))%22".
• Adding a wildcard symbol may retrieve word variants: %22great britain %((2f colonies) or (((((et colonies) OR (les colonies))) or (_ colonies)))) %((2f administration) or (trade administration))%22*.
