• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu ((van hac) OR (van ha)) ((tuc van) OR (thuc van)) doanh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu ((van hac) or (van ha)) ((tuc van) OR (thuc van)) doanh van cua tre*".
