• 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 ((((gharddtt OR harm) OR head) OR (((hardo OR (har OR (hardt OR hart))) OR (hardsh OR bharti)) OR (hardmidm OR harddm))) 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 ((((gharddtt or harm) or head) or (((hardo or (har or (hardt OR hart))) or (hardsh or bharti)) or (hardmidm or harddm))) 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 ((((gharddtt or harm) or head) or (((hardo or (har or (hardt OR hart))) or (hardsh or bharti)) or (hardmidm or harddm))) or grant)) counterinsurgency study ;*.
