• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chieu xanh)) - thanh hong quan thong cong ((tan thanh) OR (toan thanh)) lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (chieu xanh)) - thanh hong quan thong cong ((tan thanh) OR (toan thanh)) lap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (chieu xanh)) - thanh hong quan thong cong ((tan thanh) OR (toan thanh)) lap*.
