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