unis administration » unix administration, his administration, its administration
csf administration » self administration, union administration
2f administration » trf administration, self administration, delf administration
8 administration » 8 administrative, 2008 administration
great brittain » great britian, great britain's
et colonies » her colonies, des colonies, les colonies
p colonies » _ colonies, her colonies, des 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: %((great brittain) OR (great britain)) %((p colonies) OR (et colonies)) %((((2f administration) OR (8 administration))) OR (((csf administration) OR (unis administration))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((great brittain) or (great britain)) %((p colonies) or (et colonies)) %((((2f administration) or (8 administration))) or (((csf administration) OR (unis administration))))%22".
• Adding a wildcard symbol may retrieve word variants: %((great brittain) or (great britain)) %((p colonies) or (et colonies)) %((((2f administration) or (8 administration))) or (((csf administration) OR (unis administration))))%22*.
