• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty lang xa hoi. hieu viec ((cac le) OR (cach le)) ((van danh) OR (van doanh)) vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty lang xa hoi. hieu viec ((cac le) or (cach le)) ((van danh) OR (van doanh)) vai cuu tre*".
