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