• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach y lang xa hoi. ((thien van) OR (thi van)) thay nuoc ((va hanh) OR (va danh)) ve cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y lang xa hoi. ((thien van) OR (thi van)) thay nuoc ((va hanh) or (va danh)) ve cau treo".
