• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - ((hanh tranh) OR (hanh trinh)) cua khong cong tan ((toan tai) or (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((hanh tranh) OR (hanh trinh)) cua khong cong tan ((toan tai) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh tranh) OR (hanh trinh)) cua khong cong tan ((toan tai) or (toan cao))*".
