• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y tang ma hoi. hieu ve cac ((suc va) OR (tuc va)) thanh dai ((cau treo) OR (cua tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y tang ma hoi. hieu ve cac ((suc va) OR (tuc va)) thanh dai ((cau treo) or (cua tre))".
