• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) y lang xa hoi. hieu qua thanh truc va danh va ((cuu tre) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y lang xa hoi. hieu qua thanh truc va danh va ((cuu tre) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y lang xa hoi. hieu qua thanh truc va danh va ((cuu tre) or (cau tren))*".
