• If you are trying to use Boolean operators, they must be ALL CAPS: %zgreat britain %((((_ colonies) OR (p colonies))) OR (et colonies)) %((2f administration) OR (((2.2 administration) OR (((22 administration) OR (r2 administration))))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%zgreat britain %((((_ colonies) or (p colonies))) or (et colonies)) %((2f administration) or (((2.2 administration) or (((22 administration) OR (r2 administration))))))%22".
