Perhaps you should try some spelling variations:
welfare administration » revenue administration
xgreat britain » zgreat britain, great brittain, great britains
les colonies » des colonies, her colonies
et colonies » her colonies, des colonies, ant colonies
_ colonies » _ colonial

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) OR (great britain)) %((((et colonies) OR (les colonies))) OR (_ colonies)) %welfare administration%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((xgreat britain) or (great britain)) %((((et colonies) OR (les colonies))) or (_ colonies)) %welfare administration%22*".
