• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu sang) OR (hieu lang))) OR (chieu sach)) - thanh thong tu thong cong van quang nam~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sang) OR (hieu lang))) or (chieu sach)) - thanh thong tu thong cong van quang nam~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu sang) OR (hieu lang))) or (chieu sach)) - thanh thong tu thong cong van quang nam*.
