find command usage

I usually ise find to search a file or name on the unix, since I am not administrator, there will be many line appear 'cannot access',usually a hundred of lines. How can I prevent this line coming out? only show I want?
The command I use is :

find / -name abcdef -print

Thank all expert.

Redirect all error messages to /dev/null

find / -name abcdef -print 2> /dev/null
