cong doan » cong dan, cong hoan, dong doanh
ho chieu » hoc thieu, doi chieu, mot chieu
luan han » luan hoan, luan phan, luan van
han cong » phan cong, hang cong, hanh cong

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - canh tranh luan han cong doan ((phan cac) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - canh tranh luan han cong doan ((phan cac) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - canh tranh luan han cong doan ((phan cac) or (phan tu))*.
