• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR grand) OR hard) OR (had OR land)) OR (bank OR bonds)) OR ((((igrayd OR (ggrandtd OR ggraindtd)) OR (grewe OR (graw OR grow))) OR (gran OR ((grant OR (igrandts OR iirandts)) OR irande))) OR brain)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or grand) or hard) or (had or land)) or (bank or bonds)) or ((((igrayd or (ggrandtd or ggraindtd)) or (grewe or (graw or grow))) or (gran or ((grant or (igrandts OR iirandts)) or irande))) or brain)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or grand) or hard) or (had or land)) or (bank or bonds)) or ((((igrayd or (ggrandtd or ggraindtd)) or (grewe or (graw or grow))) or (gran or ((grant or (igrandts OR iirandts)) or irande))) or brain)) counterinsurgency study ;*.
