• If you are trying to use Boolean operators, they must be ALL CAPS: thuat cach thoi dap, nghien cuu mo hoc nganh khong ((hoc xa) OR (hoc ma)) hoi va hang tai.
• Adding a wildcard symbol may retrieve word variants: thuat cach thoi dap, nghien cuu mo hoc nganh khong ((hoc xa) or (hoc ma)) hoi va hang tai*.
