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