• Performing a fuzzy search may retrieve terms with similar spellings: tu sach v nang ma hoi. thieu nien chat xuc ((va dung) OR (va duong)) tai ((su triet) or (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v nang ma hoi. thieu nien chat xuc ((va dung) OR (va duong)) tai ((su triet) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v nang ma hoi. thieu nien chat xuc ((va dung) OR (va duong)) tai ((su triet) or (va thiet))".
