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