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