• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((cao hoi) OR (cao hoc)). hieu su cham xuc va dan ((dau cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((cao hoi) OR (cao hoc)). hieu su cham xuc va dan ((dau cua) or (dai cua)) te".
