OR ("chain management contracts."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((((("firm management case.") OR ("firm management issues."))) OR ("fisheries management contract."))) OR ((("waste management entity.") OR ("waste management activity."))))) OR ((("demand management _.") OR ("cash management concepts."))))) OR ((("change management contracts.") OR ("chain management contracts.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((((\"firm management case.\") or (\"firm management issues.\"))) or (\"fisheries management contract.\"))) or (((\"waste management entity.\") or (\"waste management activity.\"))))) or (((\"demand management _.\") or (\"cash management concepts.\"))))) or (((\"change management contracts.\") OR (\"chain management contracts.\"))))".

• Adding a wildcard symbol may retrieve word variants: (((((((((("firm management case.") or ("firm management issues."))) or ("fisheries management contract."))) or ((("waste management entity.") or ("waste management activity."))))) or ((("demand management _.") or ("cash management concepts."))))) or ((("change management contracts.") OR ("chain management contracts."))))*.
