• If you are trying to use Boolean operators, they must be ALL CAPS: tu cach thoi tap, nghien cuu mon hoc nganh khong thuoc xa hoi van ((dong tu) OR (dong tai))~.
• Adding a wildcard symbol may retrieve word variants: tu cach thoi tap, nghien cuu mon hoc nganh khong thuoc xa hoi van ((dong tu) or (dong tai))*.
