A good query when you search something in the dictionary (here info about 'statistics'):
SQL> Col table_name format a30 heading "View"
SQL> Col comments format a85 heading "Comment" word_wrap
SQL> Select table_name, comments
2 from dict
3 where lower(comments) like '%statistics%'
4 and table_name like 'DBA\_%' escape '\'
5 and table_name not like 'DBA\_HIST%' escape '\'
6 order by 1
