• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR ranks) OR hard) OR (had OR land)) OR (band OR bond)) OR (((((((grants OR migrants) 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: "(((((rand or ranks) or hard) or (had or land)) or (band or bond)) or (((((((grants OR migrants) 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: (((((rand or ranks) or hard) or (had or land)) or (band or bond)) or (((((((grants OR migrants) or ghana) or (grain or grained)) or ibanktd) or grad) or (gran or grand)) or graint)) counterinsurgency study ;*.
