luong quan » thong quan, duong qua
van thien » van tien, van chien, van thiet
luan phan » luan van, luan hoan
phan kiem » phan kien, phan mem, van kiem
kiem soat » kiem toan
van hien » van hieu, van tien

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tinh luong quan ((van thien) OR (van hien)) hoat ) or ( trinh dung luan phan kiem soat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh luong quan ((van thien) OR (van hien)) hoat ) OR ( trinh dung luan phan kiem soat )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh luong quan ((van thien) OR (van hien)) hoat ) or ( trinh dung luan phan kiem soat ))".
• Adding a wildcard symbol may retrieve word variants: (( tinh luong quan ((van thien) OR (van hien)) hoat ) or ( trinh dung luan phan kiem soat ))*.
