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