• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - hanh ((((hang cua) OR (hang ca))) OR (mang cua)) nhung cong dan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - hanh ((((hang cua) OR (hang ca))) or (mang cua)) nhung cong dan toan ban".
