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