• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh trung ((cua thong) OR (ca thuong)) cong ((san thanh) OR (ban thanh)) mau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh trung ((cua thong) or (ca thuong)) cong ((san thanh) OR (ban thanh)) mau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh trung ((cua thong) or (ca thuong)) cong ((san thanh) OR (ban thanh)) mau*.
