• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach khanh ha thi đong luc ) OR ( thuat lanh nganh ((khoa phu) OR (hoa phu)) đong luc ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach khanh ha thi đong luc ) or ( thuat lanh nganh ((khoa phu) OR (hoa phu)) đong luc ))*".
