• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hand) OR (had OR land)) OR (band OR bonds)) OR ((((((gray OR (migrandts OR grandts)) OR rain) OR granted) OR (rawe OR raw)) OR gran) OR (ggaint OR ((grandt OR grand) OR grants)))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hand) or (had or land)) or (band or bonds)) or ((((((gray or (migrandts or grandts)) or rain) or granted) or (rawe or raw)) or gran) or (ggaint or ((grandt OR grand) or grants)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hand) or (had or land)) or (band or bonds)) or ((((((gray or (migrandts or grandts)) or rain) or granted) or (rawe or raw)) or gran) or (ggaint or ((grandt OR grand) or grants)))) counterinsurgency study ;*.
