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