• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang mai) OR (nang tai)) hoi. lieu va cam xuc ((ban danh) OR (ban dan)) vi su viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang mai) OR (nang tai)) hoi. lieu va cam xuc ((ban danh) or (ban dan)) vi su viet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang mai) OR (nang tai)) hoi. lieu va cam xuc ((ban danh) or (ban dan)) vi su viet*.
