Perhaps you should try some spelling variations:
self administration » welfare administration
22great britain » great britain, xgreat britain, great britains
great brittain » great britain, great britian, great britain's
zgreat britain » great britain, xgreat britain, great britains

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