• If you are trying to use Boolean operators, they must be ALL CAPS: (((( tu sach moi tai nguoi ) OR ( tu cach hoc gap nguoi ))) OR ( te bach toc tay nguoi ))~.
• Adding a wildcard symbol may retrieve word variants: (((( tu sach moi tai nguoi ) or ( tu cach hoc gap nguoi ))) or ( te bach toc tay nguoi ))*.
