Perhaps you should try some spelling variations:
"farm management controls." » "farm management contract.", "farm management tools.", "farm management functions.", "cash management controls.", "bank management controls.", "data management controls."
"reform management a." » "firm management a.", "reform management _."
"demand management data." » "debt management data.", "demand management case."
"road management review." » "chain management review."

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

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