• If you are trying to use Boolean operators, they must be ALL CAPS: ((((san OR (hand OR (band OR bank))) OR (had OR land)) OR (bond OR bonds)) OR ((((grantd OR (grandtd OR granted)) OR (grawe OR (grave OR grace))) OR (gran OR graw)) OR (((bgain OR gain) OR rain) OR grain))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((san or (hand or (band or bank))) or (had or land)) or (bond or bonds)) or ((((grantd or (grandtd or granted)) or (grawe or (grave OR grace))) or (gran or graw)) or (((bgain or gain) or rain) or grain))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((san or (hand or (band or bank))) or (had or land)) or (bond or bonds)) or ((((grantd or (grandtd or granted)) or (grawe or (grave OR grace))) or (gran or graw)) or (((bgain or gain) or rain) or grain))) counterinsurgency study ;*.
