tu sach » thu sach, su sach, te sach
lang xa » lang ha, dang xay, lang van
van cau » van dau, van chat, toan cau
van hau » van ha, van hai, van dau
va danh » va dinh, va dan, va hanh
y lang » o lang, _ lang, tay lang

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. hieu ((van cau) OR (van hau)) duc va danh dau ve triet".
• Adding a wildcard symbol may retrieve word variants: tu sach y lang xa hoi. hieu ((van cau) OR (van hau)) duc va danh dau ve triet*.
