• The words AND, OR and NOT may confuse the search; try adding quotes: "thu mach hoc tap, nghiem thuc dung ((co nganh) OR (hoc nganh)) hoa hoc xa hoi dan ca van".
• Adding a wildcard symbol may retrieve word variants: thu mach hoc tap, nghiem thuc dung ((co nganh) OR (hoc nganh)) hoa hoc xa hoi dan ca van*.
