• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (stand OR (band OR grand))) OR land) OR ((((ghardtt OR hardm) OR head) OR (((hartdo OR (har OR hari)) OR ((harth OR hartth) OR bharmti)) OR (harmidm OR hartdddm))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (stand or (band or grand))) or land) or ((((ghardtt or hardm) or head) or (((hartdo or (har or hari)) or ((harth OR hartth) or bharmti)) or (harmidm or hartdddm))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (stand or (band or grand))) or land) or ((((ghardtt or hardm) or head) or (((hartdo or (har or hari)) or ((harth OR hartth) or bharmti)) or (harmidm or hartdddm))) or grant)) counterinsurgency study ;*.
