• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky dang) OR (ky nang)) ma hoa. thien dang ca ((dua ban) OR (dia ban)) thanh hoi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky dang) OR (ky nang)) ma hoa. thien dang ca ((dua ban) or (dia ban)) thanh hoi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky dang) OR (ky nang)) ma hoa. thien dang ca ((dua ban) or (dia ban)) thanh hoi cua tre*.
