• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty ((mang xa) OR (dang xay)) hoi. lieu va cam xuc va thanh ha ca viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty ((mang xa) or (dang xay)) hoi. lieu va cam xuc va thanh ha ca viet".
