• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach v ((tang ma) OR (tang van)) hoa. thien van thanh tuc va ((hang tai) OR (thanh hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v ((tang ma) OR (tang van)) hoa. thien van thanh tuc va ((hang tai) or (thanh hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach v ((tang ma) OR (tang van)) hoa. thien van thanh tuc va ((hang tai) or (thanh hai)) cua tre*.
