• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly hang ma hoa. hieu ((van cau) or (van hau)) thuc va danh ((hai cau) OR (hai chu)) treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly hang ma hoa. hieu ((van cau) OR (van hau)) thuc va danh ((hai cau) OR (hai chu)) treo.
