Perhaps you should try some spelling variations:
"farm management control." » "farm management contracts.", "cash management control.", "bank management control.", "data management control."
"oxford management reports." » "records management reports.", "road management reports.", "fire management reports."
"oxford management based." » "records management based.", "road management based.", "fire management based.", "oxford management board.", "oxford management issues.", "oxford management a."
"reform management based." » "firm management based.", "reform management board.", "reform management issues.", "reform management a."
"flood management case." » "land management case.", "flood management a."
"fund management reform." » "land management reform.", "demand management reform."

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

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