• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (lieu tinh)) - hanh lang dong truong ((phuong dan) OR (huong dan)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (lieu tinh)) - hanh lang dong truong ((phuong dan) OR (huong dan)) toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (lieu tinh)) - hanh lang dong truong ((phuong dan) OR (huong dan)) toan cau*.
