• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((anh tang) OR (nhanh mang)) cua truong ((dong tap) OR (dong tai)) doan ca~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((anh tang) or (nhanh mang)) cua truong ((dong tap) OR (dong tai)) doan ca~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((anh tang) or (nhanh mang)) cua truong ((dong tap) OR (dong tai)) doan ca*.
