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