OR ("farm management _."))) or ((("cash management water.") or ("cash management based."))))))) or ("basin management concepts."))~.

OR ((((("farm management a.") OR ("farm management _."))) OR ((("cash management water.") OR ("cash management based."))))))) OR ("basin management concepts.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"fire management controls.\") or (\"city management controls.\"))) or (\"firm management control.\"))) or (((((\"farm management a.\") OR (\"farm management _.\"))) or (((\"cash management water.\") or (\"cash management based.\"))))))) or (\"basin management concepts.\"))".

• Adding a wildcard symbol may retrieve word variants: (((((((("fire management controls.") or ("city management controls."))) or ("firm management control."))) or ((((("farm management a.") OR ("farm management _."))) or ((("cash management water.") or ("cash management based."))))))) or ("basin management concepts."))*.
