• 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 hard)) OR head) OR (((hardo OR (har OR hari)) OR (hartd OR bharti)) OR (haridm 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 ((((ghartt or (hardm OR hard)) or head) or (((hardo or (har or hari)) or (hartd or bharti)) or (haridm 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 ((((ghartt or (hardm OR hard)) or head) or (((hardo or (har or hari)) or (hartd or bharti)) or (haridm or harddm))) or grant)) counterinsurgency study ;*.
