• If you are trying to use Boolean operators, they must be ALL CAPS: te sach cam nang xa hoi. hieu ((ve cham) OR (va cham)) doc ((va danh) OR (va dinh)) dien cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach cam nang xa hoi. hieu ((ve cham) or (va cham)) doc ((va danh) OR (va dinh)) dien cua te*".
