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