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