• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (stand OR (bond OR grand))) OR land) OR ((((ghartt OR (chart OR harttm)) OR head) OR (((harthdo OR (har OR harm)) OR ((hartd OR harth) OR bharti)) OR harmmidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (stand or (bond or grand))) or land) or ((((ghartt or (chart or harttm)) or head) or (((harthdo or (har or harm)) or ((hartd OR harth) or bharti)) or harmmidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (stand or (bond or grand))) or land) or ((((ghartt or (chart or harttm)) or head) or (((harthdo or (har or harm)) or ((hartd OR harth) or bharti)) or harmmidm)) or grant)) counterinsurgency study ;*.
