• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh ((trinh cua) OR (trinh han)) cong ((dong dan) OR (dong danh)) toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((trinh cua) or (trinh han)) cong ((dong dan) OR (dong danh)) toan tap".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((trinh cua) or (trinh han)) cong ((dong dan) OR (dong danh)) toan tap*.
