chinh lap » chinh la, chinh luan, chinh tai
dung cong » dung trong
hoc dieu » hoc hien
lap dung » ap dung, lan dung, cap dung
cong san » cong tac
san toan » van toan, dan toan, manh toan

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((hoc chieu) OR (hoc dieu))) OR (hoc thieu)) xanh - hanh chinh lap dung cong san toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((hoc chieu) OR (hoc dieu))) or (hoc thieu)) xanh - hanh chinh lap dung cong san toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((((hoc chieu) OR (hoc dieu))) or (hoc thieu)) xanh - hanh chinh lap dung cong san toan tap*.
