• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cach thoi tap, nghiem thuoc cong coc nganh chung ((hoc xa) OR (hoc ma)) hoi van nhan van~".
• Adding a wildcard symbol may retrieve word variants: tu cach thoi tap, nghiem thuoc cong coc nganh chung ((hoc xa) OR (hoc ma)) hoi van nhan van*.
