Perhaps you should try some spelling variations:
"reform management controls." » "reform management contract.", "reform management tools.", "reform management functions.", "firm management controls."
"land management centers." » "land management water."
"land management energy." » "land management agency."
"reform management contracts." » "firm management contracts."
"flood management entity." » "flood management activity.", "flood management quality.", "flood management action.", "fund management entity."
"asset management concepts." » "debt management concepts."
"farm management control." » "bank management control.", "data management control.", "forest management control."

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: (((((("flood management entity.") OR ((("land management energy.") OR ("land management centers."))))) OR ((((("farm management control.") OR ("cash management control."))) OR ("asset management concepts."))))) OR ((("reform management controls.") OR ("reform management contracts."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"flood management entity.\") or (((\"land management energy.\") or (\"land management centers.\"))))) or (((((\"farm management control.\") or (\"cash management control.\"))) or (\"asset management concepts.\"))))) or (((\"reform management controls.\") OR (\"reform management contracts.\"))))~".
• Removing quotes may allow a broader search: (((((( flood management entity. ) or ((( land management energy. ) or ( land management centers. ))))) or ((((( farm management control. ) or ( cash management control. ))) or ( asset management concepts. ))))) or ((( reform management controls. ) OR ( reform management contracts. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((((("flood management entity.") or ((("land management energy.") or ("land management centers."))))) or ((((("farm management control.") or ("cash management control."))) or ("asset management concepts."))))) or ((("reform management controls.") OR ("reform management contracts."))))*.
