• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu xanh - ((dang trung) or (tdang trung)) cua khong trong ((san toan) OR (dan toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((dang trung) OR (tdang trung)) cua khong trong ((san toan) OR (dan toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((dang trung) or (tdang trung)) cua khong trong ((san toan) OR (dan toan)) cau*".
