• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky tang ((ma hoi) OR (mai hoi)). hieu ((van cam) OR (van nam)) tuc xa thanh vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky tang ((ma hoi) or (mai hoi)). hieu ((van cam) OR (van nam)) tuc xa thanh vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky tang ((ma hoi) or (mai hoi)). hieu ((van cam) OR (van nam)) tuc xa thanh vai cuu tre*.
