Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
hanh trang » thanh trung, canh tranh, hanh trinh
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
va duong » van duong, va tuong, va huong
toan tap » toan ban
va dung » van dung, vat dung, va ung

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sach) or (chiet tach)) - hanh trang ((va dung) OR (va duong)) cong manh toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chiet tach)) - hanh trang ((va dung) OR (va duong)) cong manh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chiet tach)) - hanh trang ((va dung) OR (va duong)) cong manh toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chiet tach)) - hanh trang ((va dung) OR (va duong)) cong manh toan tap*.
