• If you are trying to use Boolean operators, they must be ALL CAPS: ((((bonds OR (hair OR had)) OR (san OR ((band OR bond) OR grand))) OR land) OR ((((ghartt OR harm) OR heat) OR (((har OR ((harth OR (harmd OR harms)) 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 ((band or bond) or grand))) or land) or ((((ghartt or harm) or heat) or (((har or ((harth or (harmd OR harms)) 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 ((band or bond) or grand))) or land) or ((((ghartt or harm) or heat) or (((har or ((harth or (harmd OR harms)) or hadi)) or (hardtd or bhardti)) or hartidm)) or grants)) counterinsurgency study ;*.
