Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
tuong quan » truong quan, thong quan, luong quan
doi chieu » doc hieu, doi chi, ho chieu
tuong qua » duong qua, thong qua, trong qua
cong danh » cuong danh, cong dan, cong thanh
toan tap » toan ban
toan cao » toan ban

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

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - manh ((tuong qua) OR (tuong quan)) trong cong danh ((toan tap) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - manh ((tuong qua) OR (tuong quan)) trong cong danh ((toan tap) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - manh ((tuong qua) OR (tuong quan)) trong cong danh ((toan tap) or (toan cao))*.
