• If you are trying to use Boolean operators, they must be ALL CAPS: te ((bai ky) OR (ban ky)) lang ((van hoi) OR (van hoe)). hieu va nam xuc va dinh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((bai ky) or (ban ky)) lang ((van hoi) OR (van hoe)). hieu va nam xuc va dinh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((bai ky) or (ban ky)) lang ((van hoi) OR (van hoe)). hieu va nam xuc va dinh vi cua tre*.
