• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu tinh - ((anh tang) OR (((nhanh mang) OR (nhanh lang)))) cua thong cong van quan phan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - ((anh tang) or (((nhanh mang) OR (nhanh lang)))) cua thong cong van quan phan~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu tinh - ((anh tang) or (((nhanh mang) OR (nhanh lang)))) cua thong cong van quan phan*.
