• If you are trying to use Boolean operators, they must be ALL CAPS: ho chinh sach - ((hanh mang) OR (nhanh lang)) cua nhung cong thanh ((san tap) OR (han tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chinh sach - ((hanh mang) or (nhanh lang)) cua nhung cong thanh ((san tap) OR (han tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chinh sach - ((hanh mang) or (nhanh lang)) cua nhung cong thanh ((san tap) OR (han tap))*.
