• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR (hand OR band)) OR (had OR land)) OR (bank OR bonds)) OR ((((iggrand OR ggraindtd) OR (rawe OR graw)) OR (gran OR ((migrants OR igrandts) OR (irande OR grande)))) OR brain)) 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 (bank or bonds)) or ((((iggrand or ggraindtd) or (rawe or graw)) or (gran or ((migrants or igrandts) or (irande or grande)))) or brain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or (hand OR band)) or (had or land)) or (bank or bonds)) or ((((iggrand or ggraindtd) or (rawe or graw)) or (gran or ((migrants or igrandts) or (irande or grande)))) or brain)) counterinsurgency study ;*.
