• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (far OR had)) OR ((sand OR san) OR ((bank OR bond) OR grand))) OR land) OR ((((ghartt OR (hardm OR harm)) OR heat) OR ((((hari OR haiti) OR har) OR (hardtd OR bhairti)) 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 san) or ((bank or bond) or grand))) or land) or ((((ghartt or (hardm OR harm)) or heat) or ((((hari or haiti) or har) or (hardtd or bhairti)) or hartidm)) or grant)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (far or had)) or ((sand or san) or ((bank or bond) or grand))) or land) or ((((ghartt or (hardm OR harm)) or heat) or ((((hari or haiti) or har) or (hardtd or bhairti)) or hartidm)) or grant)) counterinsurgency study ;*.
