• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu xanh) OR (tieu danh)) - hanh trang cua ((nhung cong) OR (thong cong)) dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) or (tieu danh)) - hanh trang cua ((nhung cong) OR (thong cong)) dan toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) or (tieu danh)) - hanh trang cua ((nhung cong) OR (thong cong)) dan toan cau*.
