• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (air OR had)) OR (sand OR (bond OR grand))) OR land) OR ((((ghartt OR hartd) OR (heat OR head)) OR ((((haji OR harm) OR har) OR ((hardid OR harmd) OR bhairti)) OR hairtidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (air or had)) or (sand or (bond or grand))) or land) or ((((ghartt or hartd) or (heat OR head)) or ((((haji or harm) or har) or ((hardid or harmd) or bhairti)) or hairtidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (air or had)) or (sand or (bond or grand))) or land) or ((((ghartt or hartd) or (heat OR head)) or ((((haji or harm) or har) or ((hardid or harmd) or bhairti)) or hairtidm)) or grant)) counterinsurgency study ;*.
