You could probably adapt this solution that michaels provided ages ago (and which you'd have found if you bothered to search)...
michaels>  var val varchar2(5)
michaels>  exec :val := 'as'
PL/SQL procedure successfully completed.
michaels>  select distinct substr (:val, 1, 11) "Searchword",
                substr (table_name, 1, 14) "Table",
                substr (t.column_value.getstringval (), 1, 50) "Column/Value"
           from cols,
                table
                   (xmlsequence
                       (dbms_xmlgen.getxmltype ('select ' || column_name
                                                || ' from ' || table_name
                                                || ' where upper('
                                                || column_name
                                                || ') like upper(''%' || :val
                                                || '%'')'
                                               ).extract ('ROWSET/ROW/*')
                   ) t
--        where table_name in ('EMPLOYEES', 'JOB_HISTORY', 'DEPARTMENTS')
       order by "Table"
