• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien anh)) - ((hanh tranh) OR (hanh trinh)) cua nhung cong van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (thien anh)) - ((hanh tranh) OR (hanh trinh)) cua nhung cong van thanh cau*.
