• 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 (grand OR graw)) OR ((gran OR tran) OR irand)) 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 (grand or graw)) or ((gran OR tran) or irand)) 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 (grand or graw)) or ((gran OR tran) or irand)) or grant)) counterinsurgency study ;*.
