• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang ma hoa. hieu ((ve cam) OR (ve cham)) xuc va ((dinh vi) OR (dinh ve)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang ma hoa. hieu ((ve cam) or (ve cham)) xuc va ((dinh vi) OR (dinh ve)) cua te*".
