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

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