• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky tang ma hoi. ((hieu su) OR (hieu ve)) cham ((xuc van) OR (duc van)) thanh dau cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky tang ma hoi. ((hieu su) or (hieu ve)) cham ((xuc van) OR (duc van)) thanh dau cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky tang ma hoi. ((hieu su) or (hieu ve)) cham ((xuc van) OR (duc van)) thanh dau cuu tre*.
