Perhaps you should try some spelling variations:
2.2 administration » 4.2 administration, 1.2 administration, 22 administration
2f administration » csf administration, trf administration, self administration
xgreat britain » great britain, zgreat britain, great brittain
et colonies » des colonies, les colonies, ant colonies

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: %xgreat britain %((_ colonies) OR (((et colonies) OR (her colonies)))) %((((2f administration) OR (2008 administration))) OR (2.2 administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%xgreat britain %((_ colonies) or (((et colonies) OR (her colonies)))) %((((2f administration) or (2008 administration))) or (2.2 administration))%22".
• Adding a wildcard symbol may retrieve word variants: %xgreat britain %((_ colonies) or (((et colonies) OR (her colonies)))) %((((2f administration) or (2008 administration))) or (2.2 administration))%22*.
