• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach nganh) OR (sach ngan)) ((cong he) OR (cong de)) thong tien va truyen thong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach nganh) or (sach ngan)) ((cong he) OR (cong de)) thong tien va truyen thong".
