• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (hieu lang)) - hanh mang luan ((thong duong) OR (thong huong)) van thanh tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (hieu lang)) - hanh mang luan ((thong duong) OR (thong huong)) van thanh tap*".
