• If you are trying to use Boolean operators, they must be ALL CAPS: (((("su sach moi dap nguoi") OR ("su sach hoi dap nguoi"))) OR ("tu cach dung cac nguoi"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"su sach moi dap nguoi\") OR (\"su sach hoi dap nguoi\"))) or (\"tu cach dung cac nguoi\"))*".
• Removing quotes may allow a broader search: (((( su sach moi dap nguoi ) OR ( su sach hoi dap nguoi ))) or ( tu cach dung cac nguoi ))*.
