• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky sang ma hoa. ((hieu ve) OR (hieu van)) cam xuc va ((danh lai) OR (gian dan)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky sang ma hoa. ((hieu ve) OR (hieu van)) cam xuc va ((danh lai) or (gian dan)) cua tre*".
