Igor,
I think it should be:

select SUBSTR(hint, INSTR(hint,' ') + 1, LENGTH(hint) - INSTR(hint,' ')
-

1),

count(*)
from dba_outline_hints
where hint like '%INDEX%'
GROUP BY (SUBSTR(hint, INSTR(hint,' ') + 1, LENGTH(hint) - INSTR(hint,' ')
- 1));

--List of indices not used:

Select index_name
from user_indexes
where index_name not in (

Select distinct SUBSTR(hint, INSTR(hint,' ') + 1, LENGTH(hint) - INSTR(hint,' ') - 1)

      from dba_outline_hints
     where hint like '%INDEX%'
	 )

(INSTR changed)
