• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sach) OR (chieu sang)) - hanh trang cua nong thon ((dan thanh) OR (danh thanh)) bac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) or (chieu sang)) - hanh trang cua nong thon ((dan thanh) OR (danh thanh)) bac~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) or (chieu sang)) - hanh trang cua nong thon ((dan thanh) OR (danh thanh)) bac*.
