• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang mai hoi. hieu van lam luc ((van hanh) OR (van anh)) va ((chua trieu) OR (chu tri))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang mai hoi. hieu van lam luc ((van hanh) OR (van anh)) va ((chua trieu) or (chu tri))*".
