Perhaps you should try some spelling variations:
hospitals administration » customs administration
his administration » affairs administration, agents administration
its administration » agents administration, sports administration, customs administration
22great britain » xgreat britain, zgreat britain, great brittain
2f colonies » p colonies, et colonies, 4 colonies
_ colonies » _ colonial

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) OR (great britain)) %((2f colonies) OR (_ colonies)) %((its administration) OR (((his administration) OR (hospitals administration))))%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (great britain)) %((2f colonies) OR (_ colonies)) %((its administration) or (((his administration) or (hospitals administration))))%22*".
