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

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