• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach vu ((nang ma) OR (tang ma)) hoi. hieu ((ve cam) OR (va chat)) xuc va hanh hat chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach vu ((nang ma) OR (tang ma)) hoi. hieu ((ve cam) or (va chat)) xuc va hanh hat chau triet".
