• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ky sang) OR (ky nang)) ma hoa. hieu ((ve cham) OR (va cham)) xuc va danh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ky sang) or (ky nang)) ma hoa. hieu ((ve cham) OR (va cham)) xuc va danh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((ky sang) or (ky nang)) ma hoa. hieu ((ve cham) OR (va cham)) xuc va danh tai cua tre*.
