• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh trung cua nong ((cong tan) OR (cong thanh)) ((phan cau) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung cua nong ((cong tan) OR (cong thanh)) ((phan cau) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung cua nong ((cong tan) OR (cong thanh)) ((phan cau) or (phan tu))*.
