• 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.") OR ("cash 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.\") OR (\"cash 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. ) OR ( cash 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.") OR ("cash management control."))))))*.
