• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((((lang xa) OR (dang xay))) or (lang van)) hoi. lieu va xuat duoc ma doanh van cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((((lang xa) OR (dang xay))) OR (lang van)) hoi. lieu va xuat duoc ma doanh van cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((((lang xa) OR (dang xay))) or (lang van)) hoi. lieu va xuat duoc ma doanh van cua tre*".
