csf administration » self administration, union administration
zgreat britain » great britain, xgreat britain, great brittain
2f colonies » p colonies, 4 colonies, de 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: %zgreat britain %((((2f colonies) OR (_ colonies))) OR (et colonies)) %((((csf administration) OR (unis administration))) OR (trade administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%zgreat britain %((((2f colonies) OR (_ colonies))) or (et colonies)) %((((csf administration) or (unis administration))) or (trade administration))%22".
• Adding a wildcard symbol may retrieve word variants: %zgreat britain %((((2f colonies) OR (_ colonies))) or (et colonies)) %((((csf administration) or (unis administration))) or (trade administration))%22*.
