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