• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky sang ((tao hoa) or (bao hoa)). hieu van ((ca dua) OR (ca cua)) ban hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky sang ((tao hoa) OR (bao hoa)). hieu van ((ca dua) OR (ca cua)) ban hanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky sang ((tao hoa) or (bao hoa)). hieu van ((ca dua) OR (ca cua)) ban hanh vai cuu tre*".
