cua thong » cua thuong, cua khong, cua tong
ho chieu » theo chieu, doi chieu, mot chieu

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