"debt management case." » "debt management a."
"bank management control." » "basin management control.", "cash management control.", "demand management control."
"farm management contracts." » "cash management contracts.", "data management contracts.", "forest management contracts."

• Removing quotes may allow a broader search: (((((( asset management case. ) or ( debt management case. ))) or ((( bank management control. ) or ( risk management control. ))))) or ( farm management contracts. )).
• Adding a wildcard symbol may retrieve word variants: (((((("asset management case.") or ("debt management case."))) or ((("bank management control.") or ("risk management control."))))) or ("farm management contracts."))*.
