• 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 ((((((grayts OR ghana) OR (grain OR grained)) OR ibanktd) OR (grad OR graw)) OR (gran OR (grand OR gsand))) OR grant)) 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 ((((((grayts or ghana) or (grain or grained)) or ibanktd) or (grad OR graw)) or (gran or (grand or gsand))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or ranks) or hard) or (had or land)) or (band or bond)) or ((((((grayts or ghana) or (grain or grained)) or ibanktd) or (grad OR graw)) or (gran or (grand or gsand))) or grant)) counterinsurgency study ;*.
