• If you are trying to use Boolean operators, they must be ALL CAPS: (((((rand OR hard) OR (bank OR had)) OR ((gsand OR grant) OR gbond)) OR land) OR ((((ghad OR chad) OR ((((ghada OR ahada) OR gada) OR para) OR grad)) OR (charda OR chata)) OR migrants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((rand or hard) or (bank or had)) or ((gsand or grant) or gbond)) or land) or ((((ghad or chad) or ((((ghada OR ahada) or gada) or para) or grad)) or (charda or chata)) or migrants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: (((((rand or hard) or (bank or had)) or ((gsand or grant) or gbond)) or land) or ((((ghad or chad) or ((((ghada OR ahada) or gada) or para) or grad)) or (charda or chata)) or migrants)) counterinsurgency study ;*.
