Perhaps you should try some spelling variations:
"fishery management functions." » "fishery management operations.", "fishery management practices.", "fishery management education.", "fisheries management functions.", "fiscal management functions."
"fishery management controls." » "fishery management control.", "fishery management tools.", "fishery management protocols.", "fisheries management controls.", "fiscal management controls."
"farm management contracts." » "farm management controls.", "cash management contracts.", "bank management contracts.", "data management contracts."
"reform management contract." » "reform management control.", "firm management contract."
"flood management a." » "land management a.", "fund management a.", "flood management _."
"flood management data." » "land management data.", "fund management data.", "flood management case."
"fire management concepts." » "case management concepts.", "zone management concepts.", "city management concepts."
"side management concepts." » "case management concepts.", "zone management concepts.", "service 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: (((((("farm management contracts.") OR ((("flood management a.") OR ("flood management data."))))) OR ((((("fishery management controls.") OR ("fishery management functions."))) OR ((("fire management concepts.") OR ("side management concepts."))))))) OR ("reform management contract."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"farm management contracts.\") or (((\"flood management a.\") or (\"flood management data.\"))))) or (((((\"fishery management controls.\") OR (\"fishery management functions.\"))) or (((\"fire management concepts.\") or (\"side management concepts.\"))))))) or (\"reform management contract.\"))~".
• Removing quotes may allow a broader search: (((((( farm management contracts. ) or ((( flood management a. ) or ( flood management data. ))))) or ((((( fishery management controls. ) OR ( fishery management functions. ))) or ((( fire management concepts. ) or ( side management concepts. ))))))) or ( reform management contract. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("farm management contracts.") or ((("flood management a.") or ("flood management data."))))) or ((((("fishery management controls.") OR ("fishery management functions."))) or ((("fire management concepts.") or ("side management concepts."))))))) or ("reform management contract."))*.
