Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
nhanh lang » nhanh quang, nhanh thang, nhan dang
chau tinh » cuu tinh, ha tinh, cua tinh
luan hoan » luan van
luan phan » luan van
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu tinh) OR (chau tinh)) - nhanh lang ((luan hoan) or (luan phan)) huong dan than cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu tinh) OR (chau tinh)) - nhanh lang ((luan hoan) OR (luan phan)) huong dan than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu tinh) OR (chau tinh)) - nhanh lang ((luan hoan) or (luan phan)) huong dan than cap".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu tinh) OR (chau tinh)) - nhanh lang ((luan hoan) or (luan phan)) huong dan than cap*.
