• If you are trying to use Boolean operators, they must be ALL CAPS: (( su mach ((cua ve) OR (cua vi)) gioi cong thong tin ) OR ( su sach che le nguoi cay trong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su mach ((cua ve) OR (cua vi)) gioi cong thong tin ) or ( su sach che le nguoi cay trong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( su mach ((cua ve) OR (cua vi)) gioi cong thong tin ) or ( su sach che le nguoi cay trong tin ))*.
