Perhaps you should try some spelling variations:
self administration » welfare administration
csf administration » unis administration, union administration
2f administration » trf administration, delf administration, seif administration
les colonies » des colonies, her colonies
2f colonies » p colonies, 4 colonies, de colonies
et colonies » her colonies, des colonies, ant colonies
_ colonies » _ colonial

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