Detect Function-based indexes

Question: What can I do to see if I have function-based indexes?

Answer:  To see counts of function-based indexes, you can run these queries:

prompt *******************************************************
prompt This script will count all index types 
prompt for non-standard schema owners
prompt *******************************************************

col c1 heading 'Owner' format a20
col c2 heading 'Index|type' format a25
col c3 heading 'Count' format 999,999 

break on c1 skip 1 

select distinct
   owner c1,
   index_type c2,
   count(*)
from
   dba_indexes
where
   index_type not in ('NORMAL','LOB')
and
   owner not in (
   'APEX_040200', 
   'MDSYS',
   'OUTLN',
   'CTXSYS', 
   'OLAPSYS', 
   'FLOWS_FILES', 
   'SYSTEM', 
   'DVSYS',
   'AUDSYS', 
   'DBSNMP', 
   'GSMADMIN_INTERNAL', 
   'OJVMSYS', 
   'ORDSYS', 
   'XDB', 
   'ORDDATA', 
   'SYS', 
   'WMSYS',
   'LBACSYS') 
group by
   owner,
   index_type
order by
   owner,
   index_type;
