• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach lo) or (sach ty)) hang ma hoi. thien van lam truoc ((va danh) OR (va dan)) hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach lo) OR (sach ty)) hang ma hoi. thien van lam truoc ((va danh) OR (va dan)) hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach lo) or (sach ty)) hang ma hoi. thien van lam truoc ((va danh) OR (va dan)) hai cau treo".
