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