• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ((ha hoi) OR (ha noi)). lieu va cam xuc va ((thanh vai) OR (thanh van)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ((ha hoi) or (ha noi)). lieu va cam xuc va ((thanh vai) OR (thanh van)) cua tre*".
