Perhaps you should try some spelling variations:
"data management controls." » "data management contract.", "data management functions.", "data management protocols.", "debt management controls.", "demand management controls.", "chain management controls."
"farm management entity." » "farm management energy.", "farm management activity.", "farm management quality.", "forest management entity.", "chain management entity.", "basin management entity."
"bank management entity." » "bank management energy.", "bank management activity.", "bank management quality.", "basin management entity.", "risk management entity.", "demand management entity."
"reform management control." » "firm management control."
"cash management concepts." » "asset management concepts."
"city management tools." » "case management tools.", "crop management tools.", "security management tools."
"fire management contracts." » "side management contracts.", "case management contracts.", "zone 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 entity.") OR ("bank management entity."))) or ("cash management concepts."))) or ((("reform management control.") or ((("data management controls.") or ("city management tools."))))))) or ("fire management contracts."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("farm management entity.") OR ("bank management entity."))) OR ("cash management concepts."))) OR ((("reform management control.") OR ((("data management controls.") OR ("city management tools."))))))) OR ("fire management contracts.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"farm management entity.\") OR (\"bank management entity.\"))) or (\"cash management concepts.\"))) or (((\"reform management control.\") or (((\"data management controls.\") or (\"city management tools.\"))))))) or (\"fire management contracts.\"))".
• Removing quotes may allow a broader search: (((((((( farm management entity. ) OR ( bank management entity. ))) or ( cash management concepts. ))) or ((( reform management control. ) or ((( data management controls. ) or ( city management tools. ))))))) or ( fire management contracts. )).
• Adding a wildcard symbol may retrieve word variants: (((((((("farm management entity.") OR ("bank management entity."))) or ("cash management concepts."))) or ((("reform management control.") or ((("data management controls.") or ("city management tools."))))))) or ("fire management contracts."))*.
