• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chieu sach) OR (chieu xanh))) OR (chieu sang)) - nhanh lang cua thuong cong dan khan ap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu sach) OR (chieu xanh))) or (chieu sang)) - nhanh lang cua thuong cong dan khan ap~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu sach) OR (chieu xanh))) or (chieu sang)) - nhanh lang cua thuong cong dan khan ap*.
