• If you are trying to use Boolean operators, they must be ALL CAPS: %great britain %((p colonies) OR (((et colonies) OR (((her colonies) OR (_ colonies)))))) %((((((2f administration) OR (csf administration))) OR (8 administrative))) OR (2.2 administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((p colonies) or (((et colonies) or (((her colonies) OR (_ colonies)))))) %((((((2f administration) or (csf administration))) or (8 administrative))) or (2.2 administration))%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((p colonies) or (((et colonies) or (((her colonies) OR (_ colonies)))))) %((((((2f administration) or (csf administration))) or (8 administrative))) or (2.2 administration))%22*.
