• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ty lang xa hoi. ((hieu van) OR (hieu va)) cau luc va ((dan loai) OR (dang loai)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ty lang xa hoi. ((hieu van) OR (hieu va)) cau luc va ((dan loai) or (dang loai)) cuu tre*".
