Perhaps you should try some spelling variations:
management controls » management control, management contracts, management tools
management concepts » management contracts
management contract » management contracts, management control
management energy » management centers, management agency
management entity » management activity, management quality, management centers

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 energy) OR (management entity))) OR (management concepts)). ) OR ( firm ((management controls) OR (management contract)). ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( oxford ((((management energy) or (management entity))) or (management concepts)). ) or ( firm ((management controls) OR (management contract)). ))~".
• Adding a wildcard symbol may retrieve word variants: (( oxford ((((management energy) or (management entity))) or (management concepts)). ) or ( firm ((management controls) OR (management contract)). ))*.
