Clob objects in search form

Question

Hello.
I am trying to build a search form for my DB following the instructions of the "Developing Rich Web Applications with Oracle ADF" tutorial.
One of the attributes I want to search (which is a field of a table in the DB) is of the type CLOB, but it is marked as non-queryable, and the checkbox is disabled so I cannot make it queryable.
Is there any way to query CLOBs using the built-in search form? I know CLOBs can be queryed in Oracle.
Thank you very much.

Timo,
You're confusing Oracle Text (or whatever it's called now) with CLOB datatype , although a text index on a clob column would be ok.
You can use LIKE on clob columns, but not direct comparison with a string:
