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