• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (air OR had)) OR (sand OR (band OR grand))) OR land) OR ((((gharddtt OR hard) OR head) OR (((hardo OR (har OR hardy)) OR (hardsh OR (bharti OR bharmti))) OR (hardmidm OR harddm))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (sand or (band or grand))) or land) or ((((gharddtt or hard) or head) or (((hardo or (har or hardy)) or (hardsh or (bharti OR bharmti))) or (hardmidm or harddm))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (sand or (band or grand))) or land) or ((((gharddtt or hard) or head) or (((hardo or (har or hardy)) or (hardsh or (bharti OR bharmti))) or (hardmidm or harddm))) or grant)) counterinsurgency study ;*.
