• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((((2f colonies) or (_ colonies))) or (((et colonies) or (les colonies)))) %((((2f administration) or (trf administration))) or (((csf administration) OR (self administration))))%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((((2f colonies) or (_ colonies))) or (((et colonies) or (les colonies)))) %((((2f administration) or (trf administration))) or (((csf administration) OR (self administration))))%22*.
