• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cach hoc ma nguoi ) OR ((( te hinh hoc toc nguoi ) OR ( te dich hoc hoa nguoi ))))~.
• Adding a wildcard symbol may retrieve word variants: (( tu cach hoc ma nguoi ) or ((( te hinh hoc toc nguoi ) or ( te dich hoc hoa nguoi ))))*.
