• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chiet tach)) - thanh trung va nhung ((cong anh) OR (hong anh)) luan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chiet tach)) - thanh trung va nhung ((cong anh) OR (hong anh)) luan ban".
