• If you are trying to use Boolean operators, they must be ALL CAPS: (((("coastal zone management") OR ((((("coastal dune management") OR ("coastal line management"))) OR ("coastal dunes management"))))) OR ("coastal bone management")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"coastal zone management\") or (((((\"coastal dune management\") OR (\"coastal line management\"))) or (\"coastal dunes management\"))))) or (\"coastal bone management\"))".
• Removing quotes may allow a broader search: (((( coastal zone management ) or ((((( coastal dune management ) OR ( coastal line management ))) or ( coastal dunes management ))))) or ( coastal bone management )).
• Adding a wildcard symbol may retrieve word variants: (((("coastal zone management") or ((((("coastal dune management") OR ("coastal line management"))) or ("coastal dunes management"))))) or ("coastal bone management"))*.
