• If you are trying to use Boolean operators, they must be ALL CAPS: (( phong tri xuan van. boi duong uoc mo ) OR ( nhung thi que lang. boi dong hoc moi ))~.
• Adding a wildcard symbol may retrieve word variants: (( phong tri xuan van. boi duong uoc mo ) or ( nhung thi que lang. boi dong hoc moi ))*.
