• If you are trying to use Boolean operators, they must be ALL CAPS: (( oxford ((((((management agency) OR (management centers))) OR (((management entity) OR (((management activity) OR (management facility))))))) OR (management concepts)). ) OR ( city management controls. ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( oxford ((((((management agency) or (management centers))) or (((management entity) or (((management activity) OR (management facility))))))) or (management concepts)). ) or ( city management controls. ))~".
• Adding a wildcard symbol may retrieve word variants: (( oxford ((((((management agency) or (management centers))) or (((management entity) or (((management activity) OR (management facility))))))) or (management concepts)). ) or ( city management controls. ))*.
