Perhaps you should try some spelling variations:
"flood management controls." » "flood management control.", "flood management tools.", "flood management concepts.", "land management controls."
"flood management contract." » "flood management control.", "land management contract."
"oxford management contracts." » "oxford management controls.", "records management contracts.", "farm management contracts.", "road management contracts."
"reform management contracts." » "reform management controls.", "farm management contracts.", "firm management contracts."
"fund management reports." » "fund management reform.", "land management reports.", "demand management reports."

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: (("fund management reports.") OR ((((("flood management controls.") OR ("flood management contract."))) OR ((("oxford management contracts.") OR ("reform management contracts."))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fund management reports.\") or (((((\"flood management controls.\") or (\"flood management contract.\"))) or (((\"oxford management contracts.\") OR (\"reform management contracts.\"))))))~".
• Removing quotes may allow a broader search: (( fund management reports. ) or ((((( flood management controls. ) or ( flood management contract. ))) or ((( oxford management contracts. ) OR ( reform management contracts. ))))))~.
• Adding a wildcard symbol may retrieve word variants: (("fund management reports.") or ((((("flood management controls.") or ("flood management contract."))) or ((("oxford management contracts.") OR ("reform management contracts."))))))*.
