• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu lang - ((thanh trung) OR (thanh tung)) van hung ((tuong van) OR (trong van)) chat tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu lang - ((thanh trung) OR (thanh tung)) van hung ((tuong van) or (trong van)) chat tap*".
