Perhaps you should try some spelling variations:
"oxford management controls." » "oxford management control.", "oxford management tools.", "oxford management concepts.", "reform management controls.", "records management controls.", "flood management controls."
"demand management contract." » "demand management control.", "land management contract."
"debt management contract." » "debt management control."
"oxford management contracts." » "oxford management controls.", "reform management contracts.", "records management contracts.", "flood management contracts."
"fund management reports." » "fund management reform.", "land management reports."

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: (("fund management reports.") OR ((((("oxford management controls.") OR ((("demand management contract.") OR ("debt management contract."))))) OR ("oxford management contracts."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fund management reports.\") or (((((\"oxford management controls.\") or (((\"demand management contract.\") OR (\"debt management contract.\"))))) or (\"oxford management contracts.\"))))~".
• Removing quotes may allow a broader search: (( fund management reports. ) or ((((( oxford management controls. ) or ((( demand management contract. ) OR ( debt management contract. ))))) or ( oxford management contracts. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("fund management reports.") or ((((("oxford management controls.") or ((("demand management contract.") OR ("debt management contract."))))) or ("oxford management contracts."))))*.
