• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tay) OR (xach tay)) ((dang xay) OR (van xay)) hoi. chieu ke cau luc va danh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tay) or (xach tay)) ((dang xay) OR (van xay)) hoi. chieu ke cau luc va danh vi cua tu*".
