• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu ((lang ha) OR (nang ma)) hoi. hieu qua cham xuc va ((danh vi) OR (dinh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu ((lang ha) or (nang ma)) hoi. hieu qua cham xuc va ((danh vi) OR (dinh vi)) cua te".
