• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoi tieu)) lang - ((thanh tang) OR (thanh thang)) ap dung cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoi tieu)) lang - ((thanh tang) OR (thanh thang)) ap dung cong dan than cau".
