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