• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR frank) OR (had OR band)) OR land) OR ((((gran OR granted) OR (grantts OR (migrants OR (migrandts OR emigrants)))) OR ((grand OR grawd) OR (graft OR grant))) OR (gband OR bank))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or frank) or (had or band)) or land) or ((((gran or granted) or (grantts or (migrants or (migrandts or emigrants)))) or ((grand OR grawd) or (graft or grant))) or (gband or bank))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or frank) or (had or band)) or land) or ((((gran or granted) or (grantts or (migrants or (migrandts or emigrants)))) or ((grand OR grawd) or (graft or grant))) or (gband or bank))) counterinsurgency study ;*.
