• If you are trying to use Boolean operators, they must be ALL CAPS: ((((rand OR hard) OR (had OR land)) OR (band OR bonds)) OR ((((((graw OR (migrants OR grandes)) OR rain) OR granted) OR (grawe OR raw)) OR grant) OR (ggaint OR (((grandt OR ggrandt) OR grantdt) OR grants)))) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((rand or hard) or (had or land)) or (band or bonds)) or ((((((graw or (migrants or grandes)) or rain) or granted) or (grawe or raw)) or grant) or (ggaint or (((grandt OR ggrandt) or grantdt) or grants)))) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((rand or hard) or (had or land)) or (band or bonds)) or ((((((graw or (migrants or grandes)) or rain) or granted) or (grawe or raw)) or grant) or (ggaint or (((grandt OR ggrandt) or grantdt) or grants)))) counterinsurgency study ;*.
