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