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