Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %great britain %((p colonies) OR (((les colonies) OR (_ colonies)))) %((((self administration) OR (8 administration))) OR (((2.2 administration) OR (1.2 administration))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((p colonies) or (((les colonies) OR (_ colonies)))) %((((self administration) or (8 administration))) or (((2.2 administration) or (1.2 administration))))%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((p colonies) or (((les colonies) OR (_ colonies)))) %((((self administration) or (8 administration))) or (((2.2 administration) or (1.2 administration))))%22*.
