• 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 ((((ghartt or hearm) or heat) or ((((harmo OR harms) or (hart or hari)) or (((harttd or parttd) or harth) or bharti)) or harmdm)) 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 ((((ghartt or hearm) or heat) or ((((harmo OR harms) or (hart or hari)) or (((harttd or parttd) or harth) or bharti)) or harmdm)) or grant)) counterinsurgency study ;*.
