• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu ((lang xa) OR (dang xay)) hoi. ((hieu ve) OR (hieu van)) cac duc gia hanh ke cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu ((lang xa) OR (dang xay)) hoi. ((hieu ve) or (hieu van)) cac duc gia hanh ke cau treo*".
