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." » "reform management reports.", "records management reports.", "fire management reports."
"oxford management based." » "reform management based.", "records management based.", "fire management based.", "oxford management board.", "oxford management issues.", "oxford management a."
"flood management case." » "land management case.", "flood management a."
"road management reports." » "land management reports.", "demand management reports.", "chain management reports."

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 ("road management reports."))) or ("fund management reform."))) or ((((("oxford 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 ("road management reports."))) OR ("fund management reform."))) OR ((((("oxford 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 (\"road management reports.\"))) or (\"fund management reform.\"))) or (((((\"oxford management based.\") or (\"flood management case.\"))) or (\"farm management control.\"))))*".
• Removing quotes may allow a broader search: (((((( oxford management reports. ) OR ( road management reports. ))) or ( fund management reform. ))) or ((((( oxford management based. ) or ( flood management case. ))) or ( farm management control. ))))*.
