• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu tinh - hanh ((((trang cua) OR (tranh cua))) OR (trung cua)) thong cong ban than cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu tinh - hanh ((((trang cua) OR (tranh cua))) or (trung cua)) thong cong ban than cao*".
