How slow is

select * from arc_44 where

     FILE_DATE >= to_date('01/01/2001', 'dd-mm-yyyy') and FILE_DATE <= to_date('15/12/2001', 'dd-mm-yyyy')

?

Why two/three indexes ( on FULL_TEXT, CONTENT and META_DATA), if one is sufficient?
Some time ago (2 weeks?) there was a thread on combining text index fields (CLOBs) into one index.
