• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky sang ((ma hoi) OR (ma hoa)). hieu van ((cau phuc) or (huu phuc)) va thanh dieu cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky sang ((ma hoi) OR (ma hoa)). hieu van ((cau phuc) OR (huu phuc)) va thanh dieu cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky sang ((ma hoi) OR (ma hoa)). hieu van ((cau phuc) or (huu phuc)) va thanh dieu cua tre*".
