• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (hieu lang)) - anh trong nha ((nhung cong) OR (tong cong)) van thanh tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (hieu lang)) - anh trong nha ((nhung cong) or (tong cong)) van thanh tap".
