• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or grand) or hard) or (had or land)) or (bank or bonds)) or ((((iband or (girandtd or gisandtd)) or graw) or (((gran OR tran) or grain) or (grant or iband))) or rain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or grand) or hard) or (had or land)) or (bank or bonds)) or ((((iband or (girandtd or gisandtd)) or graw) or (((gran OR tran) or grain) or (grant or iband))) or rain)) counterinsurgency study ;*.
