• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ty lang xa hoi. thien van lam xuc va tinh di ((cau tre) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty lang xa hoi. thien van lam xuc va tinh di ((cau tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty lang xa hoi. thien van lam xuc va tinh di ((cau tre) or (cau tren))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ty lang xa hoi. thien van lam xuc va tinh di ((cau tre) or (cau tren))*.
