• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (san OR ((bank OR bond) OR grand))) OR land) OR ((((ghartt OR harm) OR heat) OR ((((har OR hari) OR ((earth OR harmd) OR hadi)) OR (hardtd OR bhardti)) OR hartidm)) OR grants)) counterinsurgency study ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((bonds or (hair or had)) or (san or ((bank or bond) or grand))) or land) or ((((ghartt or harm) or heat) or ((((har OR hari) or ((earth or harmd) or hadi)) or (hardtd or bhardti)) or hartidm)) or grants)) counterinsurgency study ;~".
• Adding a wildcard symbol may retrieve word variants: ((((bonds or (hair or had)) or (san or ((bank or bond) or grand))) or land) or ((((ghartt or harm) or heat) or ((((har OR hari) or ((earth or harmd) or hadi)) or (hardtd or bhardti)) or hartidm)) or grants)) counterinsurgency study ;*.
