• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (hand OR band)) OR (had OR land)) OR (bond OR bonds)) OR ((((((grainy OR gain) OR grantd) OR granktd) OR (race OR rice)) OR (grand OR grow)) OR (((braint OR brain) OR raint) OR main))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or (hand OR band)) or (had or land)) or (bond or bonds)) or ((((((grainy or gain) or grantd) or granktd) or (race or rice)) or (grand or grow)) or (((braint or brain) or raint) or main))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (hand OR band)) or (had or land)) or (bond or bonds)) or ((((((grainy or gain) or grantd) or granktd) or (race or rice)) or (grand or grow)) or (((braint or brain) or raint) or main))) counterinsurgency study ;*.
