• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky ((dang ma) OR (dang mau)) hoi. ((hieu ve) OR (hieu va)) cam xuc va danh va cho tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky ((dang ma) or (dang mau)) hoi. ((hieu ve) OR (hieu va)) cam xuc va danh va cho tre*".
