Perhaps you should try some spelling variations:
management activity » management activities, management facility, management authority
management agency » management agencies, management science, management areas
management entity » management energy, management quality, management centers
city management » data management, case management, crop management
cash management » asset management

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: (( oxford ((((((management agency) OR (management control))) OR (((management entity) OR (management activity))))) OR (management contracts)). ) OR ( ((city management) OR (cash management)) contract. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( oxford ((((((management agency) or (management control))) or (((management entity) or (management activity))))) or (management contracts)). ) or ( ((city management) OR (cash management)) contract. ))~".
• Adding a wildcard symbol may retrieve word variants: (( oxford ((((((management agency) or (management control))) or (((management entity) or (management activity))))) or (management contracts)). ) or ( ((city management) OR (cash management)) contract. ))*.
