• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (air OR had)) OR (sand OR (bond OR grand))) OR land) OR ((((gharmtt OR hardy) OR heat) OR (((harttmo OR ((har OR harmd) OR harm)) OR ((harmth OR hardth) OR bharti)) OR harmtidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (sand or (bond or grand))) or land) or ((((gharmtt or hardy) or heat) or (((harttmo or ((har or harmd) or harm)) or ((harmth OR hardth) or bharti)) or harmtidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (sand or (bond or grand))) or land) or ((((gharmtt or hardy) or heat) or (((harttmo or ((har or harmd) or harm)) or ((harmth OR hardth) or bharti)) or harmtidm)) or grant)) counterinsurgency study ;*.
