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