• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu xanh)) - ((danh thanh) OR (nhanh thanh)) va phuong cong dan phan dau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu xanh)) - ((danh thanh) or (nhanh thanh)) va phuong cong dan phan dau*".
