Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
va thanh » gia thanh, ban thanh, va tinh
luat tuc » luat thue
thi van » thi lan, thi hanh, thi nang
van cau » van dau, van hau, van chat
cau xuc » cam xuc, cau luc, cau truc
va hanh » van hanh, va danh, ban hanh
y lang » o lang, tay lang, yen lang
_ lang » o lang, _ land

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ((y lang) or (_ lang)) ha noi. thi van cau xuc ((va hanh) OR (va thanh)) trinh luat tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((y lang) OR (_ lang)) ha noi. thi van cau xuc ((va hanh) OR (va thanh)) trinh luat tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((y lang) or (_ lang)) ha noi. thi van cau xuc ((va hanh) OR (va thanh)) trinh luat tuc".
• Adding a wildcard symbol may retrieve word variants: toc sach ((y lang) or (_ lang)) ha noi. thi van cau xuc ((va hanh) OR (va thanh)) trinh luat tuc*.
