• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR (band OR grand))) OR land) OR ((((ghartdddtt OR (hardm OR hartdm)) OR head) OR (((hard OR (har OR hadi)) OR (hartd OR bharti)) OR (harmidm OR hardddm))) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartdddtt or (hardm OR hartdm)) or head) or (((hard or (har or hadi)) or (hartd or bharti)) or (harmidm or hardddm))) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or (band or grand))) or land) or ((((ghartdddtt or (hardm OR hartdm)) or head) or (((hard or (har or hadi)) or (hartd or bharti)) or (harmidm or hardddm))) or grant)) counterinsurgency study ;*.
