• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) y nang xa hoi. hieu viec cac co van danh vai ((cuu tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y nang xa hoi. hieu viec cac co van danh vai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) y nang xa hoi. hieu viec cac co van danh vai ((cuu tre) or (cau treo))*".
