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