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