• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang xa) OR (hoang van)) hoi. hieu van cam xuc va hanh ((va cua) OR (va chua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) or (hoang van)) hoi. hieu van cam xuc va hanh ((va cua) OR (va chua)) triet".
