• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (sand OR ((band OR bond) OR grand))) OR land) OR ((((gharttt OR (hardm OR hardy)) OR head) OR ((((haro OR carto) OR (har OR hari)) OR (hartd OR bharti)) OR harmidm)) 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 bond) or grand))) or land) or ((((gharttt or (hardm OR hardy)) or head) or ((((haro or carto) or (har or hari)) or (hartd or bharti)) or harmidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (sand or ((band or bond) or grand))) or land) or ((((gharttt or (hardm OR hardy)) or head) or ((((haro or carto) or (har or hari)) or (hartd or bharti)) or harmidm)) or grant)) counterinsurgency study ;*.
