• If you are trying to use Boolean operators, they must be ALL CAPS: %22great britain %((4 colonies) OR (((et colonies) OR (des colonies)))) %((((2f administration) OR (unis administration))) OR (((((self administration) OR (welfare administration))) OR (trade administration))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %((4 colonies) or (((et colonies) or (des colonies)))) %((((2f administration) or (unis administration))) or (((((self administration) OR (welfare administration))) or (trade administration))))%22".
• Adding a wildcard symbol may retrieve word variants: %22great britain %((4 colonies) or (((et colonies) or (des colonies)))) %((((2f administration) or (unis administration))) or (((((self administration) OR (welfare administration))) or (trade administration))))%22*.
