• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (bank OR bonds)) OR ((((iggrand OR gggrandtd) OR (grawe OR (graw OR raw))) OR (gran OR ((grantts OR (irandts OR igrandts)) OR grainde))) OR brain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (bank or bonds)) or ((((iggrand or gggrandtd) or (grawe or (graw OR raw))) or (gran or ((grantts or (irandts or igrandts)) or grainde))) or brain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (bank or bonds)) or ((((iggrand or gggrandtd) or (grawe or (graw OR raw))) or (gran or ((grantts or (irandts or igrandts)) or grainde))) or brain)) counterinsurgency study ;*.
