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