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

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

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