• If you are trying to use Boolean operators, they must be ALL CAPS: (( vu sach ca me gioi cog thuong tin ) OR ( vu sach dao me gioi ((co thong) OR (co trong)) tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( vu sach ca me gioi cog thuong tin ) or ( vu sach dao me gioi ((co thong) or (co trong)) tin ))*.
