• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((lang xa) OR (lang ha)) hoi. hieu qua cao xuc va ((hang thai) OR (hang tai)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((lang xa) OR (lang ha)) hoi. hieu qua cao xuc va ((hang thai) or (hang tai)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((lang xa) OR (lang ha)) hoi. hieu qua cao xuc va ((hang thai) or (hang tai)) cuu tre*.
