• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sang)) - hanh trung tuan nhung ((song van) OR (duong van)) tuan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu sang)) - hanh trung tuan nhung ((song van) or (duong van)) tuan cau*".
