• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ky nang ((ma hoi) or (ma hoa)). ((hieu va) OR (hieu qua)) cao tuc va danh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky nang ((ma hoi) OR (ma hoa)). ((hieu va) OR (hieu qua)) cao tuc va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky nang ((ma hoi) or (ma hoa)). ((hieu va) OR (hieu qua)) cao tuc va danh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu dan ky nang ((ma hoi) or (ma hoa)). ((hieu va) OR (hieu qua)) cao tuc va danh vi cua te*.
