• 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 ((((gharddtt OR hardm) OR head) OR (((harid OR (har OR harm)) OR (hardtd OR (bharti OR bhariti))) OR (hardidm 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 ((((gharddtt or hardm) or head) or (((harid or (har or harm)) or (hardtd or (bharti OR bhariti))) or (hardidm 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 ((((gharddtt or hardm) or head) or (((harid or (har or harm)) or (hardtd or (bharti OR bhariti))) or (hardidm or hardddm))) or grant)) counterinsurgency study ;*.
