Perhaps you should try some spelling variations:
anh truong » manh truong, anh thuong, anh trong
chiet tach » chieu sach
truong cao » truong dai
nhung cong » dung cong, thong cong, hang cong
hieu lang » chieu sang, hieu quang, nhieu tang
cao nhung » cho nhung, cam nhung, cao chung
van van » van ban, tan van, san van
van vat » van chat, nhan vat

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: hoc ((hieu lang) OR (chiet tach)) - anh truong cao nhung cong ((van van) OR (van vat)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu lang) or (chiet tach)) - anh truong cao nhung cong ((van van) OR (van vat)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu lang) or (chiet tach)) - anh truong cao nhung cong ((van van) OR (van vat)) ban*.
