• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chinh) OR (thien thanh)) sach - hanh ((mang va) OR (hang va)) nhung cong san toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chinh) or (thien thanh)) sach - hanh ((mang va) OR (hang va)) nhung cong san toan ban".
• Adding a wildcard symbol may retrieve word variants: ((thi chinh) or (thien thanh)) sach - hanh ((mang va) OR (hang va)) nhung cong san toan ban*.
