• If you are trying to use Boolean operators, they must be ALL CAPS: chung thi ((xuan nang) OR (xuan hoang)). bien tap trong ((ban than) OR (ban hang))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chung thi ((xuan nang) OR (xuan hoang)). bien tap trong ((ban than) or (ban hang))*".
