• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chiet tach)) - hanh trung cua nhung ((cong danh) OR (cuong danh)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chiet tach)) - hanh trung cua nhung ((cong danh) OR (cuong danh)) toan cao".
