• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung thi que van. hai phong hoc moni ) OR ( nhung tri qua van. nuoi duong hoc mon ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thi que van. hai phong hoc moni ) or ( nhung tri qua van. nuoi duong hoc mon ))*.
