• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((anh dang) or (anh quang)) cua thanh ((long doan) OR (rong doanh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((anh dang) or (anh quang)) cua thanh ((long doan) OR (rong doanh)) toan ban*.
