Perhaps you should try some spelling variations:

hieu nganh » vien nganh, hiem ngan, nghiep nganh
tang luong » nang luong, tang cuong, hang luong
khong cong » thong cong, khong cang, chong cong
hieu manh » chieu xanh, dieu hanh, hien hanh
cong manh » cong danh, duong manh, cong thanh
anh tang » anh bang, anh dang, anh nang
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu manh) OR (hieu nganh)) - anh tang luong khong cong manh ((toan cau) or (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - anh tang luong khong cong manh ((toan cau) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (hieu nganh)) - anh tang luong khong cong manh ((toan cau) or (toan tap))".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu manh) OR (hieu nganh)) - anh tang luong khong cong manh ((toan cau) or (toan tap))*.
