• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu xanh) or (chiet tach)) - canh ((tranh cua) OR (doanh cua)) nhung cong tinh toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chiet tach)) - canh ((tranh cua) OR (doanh cua)) nhung cong tinh toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chiet tach)) - canh ((tranh cua) OR (doanh cua)) nhung cong tinh toan ban*".
