Perhaps you should try some spelling variations:
welfare administration » revenue administration
zgreat britain » great brittain, great britains, great britiain
xgreat britain » great brittain, great britains, great britiain
et colonies » her colonies, des colonies, les 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: %((((zgreat britain) OR (xgreat britain))) OR (great britain)) %((et colonies) OR (_ colonies)) %welfare administration%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((zgreat britain) OR (xgreat britain))) or (great britain)) %((et colonies) or (_ colonies)) %welfare administration%22*".
