Perhaps you should try some spelling variations:
phuong thao » phuong phap, phuong thuc
chieu sach » chinh sach, chiet tach, chieu sang
thi phuong » thi truong
doi chieu » doc hieu, doi chi, mot chieu
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
thao toan » thuat toan, thanh toan, tap toan
toan cao » toan ban, toan tap

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh ((trang cua) OR (trung cua)) thi phuong thao toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh ((trang cua) OR (trung cua)) thi phuong thao toan cao*.
