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.", "road management reports."
"oxford management water." » "reform management water.", "records management water.", "road management water.", "oxford management data.", "oxford management based.", "oxford management a."
"fund management reform." » "demand management reform."
"flood management case." » "flood management a."
"land management case." » "land management a."

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: (((("oxford management reports.") OR ("fund management reform."))) OR ((((("oxford management water.") OR ((("flood management case.") OR ("land 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 water.\") or (((\"flood management case.\") OR (\"land management case.\"))))) or (\"farm management control.\"))))~".
• Removing quotes may allow a broader search: (((( oxford management reports. ) or ( fund management reform. ))) or ((((( oxford management water. ) or ((( flood management case. ) OR ( land management case. ))))) or ( farm management control. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("oxford management reports.") or ("fund management reform."))) or ((((("oxford management water.") or ((("flood management case.") OR ("land management case."))))) or ("farm management control."))))*.
