• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((vu sach) OR (vu khach)) nganh cong khi đong luc ) OR ( su sach nhanh chong khi đong luc ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((vu sach) OR (vu khach)) nganh cong khi đong luc ) or ( su sach nhanh chong khi đong luc ))*".
