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