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