Perhaps you should try some spelling variations:
"farm management controls." » "farm management contract.", "farm management functions.", "farm management protocols.", "cash management controls.", "data management controls.", "forest management controls."
"bank management controls." » "bank management contract.", "bank management functions.", "bank management protocols.", "basin management controls.", "risk management controls.", "cash management controls."
"oxford management control." » "records management control.", "flood management control.", "road management control."
"reform management concepts." » "firm management concepts."
"fund management contracts." » "demand management contracts."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((((((("farm management controls.") OR ("bank management controls."))) or ("oxford management control."))) or ((("fund management contracts.") or ("land management tools."))))) or ("reform management concepts."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("farm management controls.") OR ("bank management controls."))) OR ("oxford management control."))) OR ((("fund management contracts.") OR ("land management tools."))))) OR ("reform management concepts.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"farm management controls.\") OR (\"bank management controls.\"))) or (\"oxford management control.\"))) or (((\"fund management contracts.\") or (\"land management tools.\"))))) or (\"reform management concepts.\"))".
• Removing quotes may allow a broader search: (((((((( farm management controls. ) OR ( bank management controls. ))) or ( oxford management control. ))) or ((( fund management contracts. ) or ( land management tools. ))))) or ( reform management concepts. )).
• Adding a wildcard symbol may retrieve word variants: (((((((("farm management controls.") OR ("bank management controls."))) or ("oxford management control."))) or ((("fund management contracts.") or ("land management tools."))))) or ("reform management concepts."))*.
