• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu lang)) - thanh tuong va trong hong ((bang than) OR (ban than)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (hieu lang)) - thanh tuong va trong hong ((bang than) or (ban than)) cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (hieu lang)) - thanh tuong va trong hong ((bang than) or (ban than)) cau*.
