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