• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc thieu) OR (((thi hien) OR (thi lien)))) xanh - hanh truong cua thong vung bai toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc thieu) or (((thi hien) OR (thi lien)))) xanh - hanh truong cua thong vung bai toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((toc thieu) or (((thi hien) OR (thi lien)))) xanh - hanh truong cua thong vung bai toan cau*.
