• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) thue hang cau hoi. thi lan thanh loc ca dan ((da cau) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) thue hang cau hoi. thi lan thanh loc ca dan ((da cau) or (dai cua)) tre*".
