• If you are trying to use Boolean operators, they must be ALL CAPS: ((((sand OR hard) OR (had OR land)) OR (bond OR bonds)) OR ((((((ray OR ((migrandts OR migrantt) OR grantdts)) OR brain) OR grantted) OR (race OR raw)) OR gran) OR (ggaint OR ((grande OR grand) OR grants)))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((sand or hard) or (had or land)) or (bond or bonds)) or ((((((ray or ((migrandts or migrantt) or grantdts)) or brain) or grantted) or (race or raw)) or gran) or (ggaint or ((grande OR grand) or grants)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((sand or hard) or (had or land)) or (bond or bonds)) or ((((((ray or ((migrandts or migrantt) or grantdts)) or brain) or grantted) or (race or raw)) or gran) or (ggaint or ((grande OR grand) or grants)))) counterinsurgency study ;*.
