• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((grand or grawd) or san) or hand) or (had or land)) or (bank or bonds)) or ((((((grant or gray) or grained) or grantsed) or (rates or raw)) or ((gran OR tran) or grain)) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((grand or grawd) or san) or hand) or (had or land)) or (bank or bonds)) or ((((((grant or gray) or grained) or grantsed) or (rates or raw)) or ((gran OR tran) or grain)) or graint)) counterinsurgency study ;*.
