• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky lang xa hoi. hieu ((qua cam) OR (qua cac)) ((tuc va) OR (truc va)) danh di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky lang xa hoi. hieu ((qua cam) or (qua cac)) ((tuc va) OR (truc va)) danh di cuu tre".
