• If you are trying to use Boolean operators, they must be ALL CAPS: (( phung thi dan lang. con duong nguoc ma ) OR ( chung thong biet lang. doi tuong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( phung thi dan lang. con duong nguoc ma ) or ( chung thong biet lang. doi tuong hoc mo ))*.
