• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach che ((ve gian) OR (ve giai)) con dong tin ) OR ( te sach cha me nguoi bon pdong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach che ((ve gian) OR (ve giai)) con dong tin ) or ( te sach cha me nguoi bon pdong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach che ((ve gian) OR (ve giai)) con dong tin ) or ( te sach cha me nguoi bon pdong tin ))*.
