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