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