va phuong » va thuong, cac phuong
cong doan » cong dan, cong hoan, dong doanh

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