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