• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (far OR had)) OR (sand OR ((band OR bond) OR grand))) OR land) OR ((((ghartt OR harm) OR heat) OR (((((hari OR harti) OR haiti) OR har) OR (hard OR bharti)) OR hartidm)) OR grant)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (far or had)) or (sand or ((band or bond) or grand))) or land) or ((((ghartt or harm) or heat) or (((((hari OR harti) or haiti) or har) or (hard or bharti)) or hartidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (far or had)) or (sand or ((band or bond) or grand))) or land) or ((((ghartt or harm) or heat) or (((((hari OR harti) or haiti) or har) or (hard or bharti)) or hartidm)) or grant)) counterinsurgency study ;*.
