• If you are trying to use Boolean operators, they must be ALL CAPS: (( thep mang lam ((tinh f.c) OR (tinh hoc)). ) OR ( tao bang nam trinh doc. )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thep mang lam ((tinh f.c) OR (tinh hoc)). ) or ( tao bang nam trinh doc. ))".
• Adding a wildcard symbol may retrieve word variants: (( thep mang lam ((tinh f.c) OR (tinh hoc)). ) or ( tao bang nam trinh doc. ))*.
