OR ("farm management control."))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("oxford management readers.") OR ("flood management centers."))) OR ((((("oxford management concepts.") OR ((("land management data.") OR ("oxford management issues."))))) OR ((("reform management control.") OR ("farm management control.")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"oxford management readers.\") or (\"flood management centers.\"))) or (((((\"oxford management concepts.\") or (((\"land management data.\") or (\"oxford management issues.\"))))) or (((\"reform management control.\") OR (\"farm management control.\"))))))".
• Removing quotes may allow a broader search: (((( oxford management readers. ) or ( flood management centers. ))) or ((((( oxford management concepts. ) or ((( land management data. ) or ( oxford management issues. ))))) or ((( reform management control. ) OR ( farm management control. )))))).
• Adding a wildcard symbol may retrieve word variants: (((("oxford management readers.") or ("flood management centers."))) or ((((("oxford management concepts.") or ((("land management data.") or ("oxford management issues."))))) or ((("reform management control.") OR ("farm management control."))))))*.
