• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((cang thang) OR (hung thang)) va thong cong tap ((toan tai) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((cang thang) OR (hung thang)) va thong cong tap ((toan tai) OR (toan ban))*.
