Oracle field lengths

[Stacy Mader]

Hi all,

I'm running Oracle 7.3.3 (I know, its rather old) under Solaris 2.5...
With
most of our tables, the maximum number of characters (varchar2)
is set to 2000 - I think this is because anything longer does not allow
you to perform a search on indexed fields...

Do the newer versions of Oracle allow you to extend the length
to beyond 2000 characters and still allow you to search?

Thanks,

    Stacy.
