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