• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (band OR grand))) OR land) OR ((((ghartt OR (hardm OR haram)) OR head) OR (((harm OR (har OR hari)) OR ((hartd OR hart) OR bcharti)) OR (hardidm OR hardidm))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartt or (hardm OR haram)) or head) or (((harm or (har or hari)) or ((hartd or hart) or bcharti)) or (hardidm or hardidm))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartt or (hardm OR haram)) or head) or (((harm or (har or hari)) or ((hartd or hart) or bcharti)) or (hardidm or hardidm))) or grant)) counterinsurgency study ;*.
