• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (bank or grand))) or land) or ((((ghartttt or hardy) or heat) or (((harms or ((har or harmd) or bharti)) or (harmdtd or (bhart OR hart))) or hartidm)) or grants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (bank or grand))) or land) or ((((ghartttt or hardy) or heat) or (((harms or ((har or harmd) or bharti)) or (harmdtd or (bhart OR hart))) or hartidm)) or grants)) counterinsurgency study ;*.
