• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (cuu tinh)) - canh tinh quang truong cong tan ((han tap) OR (han tai))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (cuu tinh)) - canh tinh quang truong cong tan ((han tap) OR (han tai))*".
