• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thi ((hang xa) OR (hoang xa)) hoi. hieu ((ve cam) OR (ve cham)) tuc va hanh va cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thi ((hang xa) OR (hoang xa)) hoi. hieu ((ve cam) or (ve cham)) tuc va hanh va cua triet".
