• If you are trying to use Boolean operators, they must be ALL CAPS: (((((sand OR ranks) OR hard) OR (had OR land)) OR (band OR bonds)) OR (((((((grants OR grantts) OR ghana) OR (grain OR grained)) OR ibanktd) OR grad) OR (gran OR grand)) OR graint)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((sand or ranks) or hard) or (had or land)) or (band or bonds)) or (((((((grants OR grantts) or ghana) or (grain or grained)) or ibanktd) or grad) or (gran or grand)) or graint)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((sand or ranks) or hard) or (had or land)) or (band or bonds)) or (((((((grants OR grantts) or ghana) or (grain or grained)) or ibanktd) or grad) or (gran or grand)) or graint)) counterinsurgency study ;*.
