• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu hang va hoi. lieu va nam mua van thanh ((((hai cua) OR (thai cua))) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu hang va hoi. lieu va nam mua van thanh ((((hai cua) OR (thai cua))) or (dai cua)) tre*".
