Perhaps you should try some spelling variations:
union administration » unix administration, unis administration, prison administration
self administration » welfare administration
2f administration » csf administration, trf administration, delf administration
xgreat britain » great britain, zgreat britain, great brittain
des colonies » her colonies, _ colonies
et colonies » her colonies, les colonies, ant colonies
p colonies » _ colonies, her colonies, les 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 %((((p colonies) OR (des colonies))) OR (et colonies)) %((((2f administration) OR (self administration))) OR (union administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%xgreat britain %((((p colonies) OR (des colonies))) or (et colonies)) %((((2f administration) or (self administration))) or (union administration))%22".
• Adding a wildcard symbol may retrieve word variants: %xgreat britain %((((p colonies) OR (des colonies))) or (et colonies)) %((((2f administration) or (self administration))) or (union administration))%22*.
