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