Issues using Oracle Text conditions

Question

Hi all,
I'm facing an issue executing a query on a VIEW using Oracle Text Indexes.
The DB version I'm using is "Enterprise 9.2.0.5".
TEST_VIEW is an sql-view that has a query on several tables where one of them has two Oracle Text indexes, one on field FIELD2 and another on FIELD3
executing this query I get 10 rows:
select *
from TEST_VIEW
where FIELD1 = 1001 -- regular condition
and (contains(FIELD2, 'Blitz') > 0 ) -- Oracle text condition
But if I add another condition on an existent Oracle Text Index, I'll get only 1 row:
select *
from TEST_VIEW
where FIELD1 = 1001
where (contains(FIELD2, 'Blitz') > 0 OR contains(FIELD3, 'Blitz') > 0)
As you can see the third condition was added using a logical OR, so I should get at least 10 rows ...
Can anyone help me ?
ThaNks in advance.
Eduardo.

Eduardo,
Without a full test case, it is hard to see if there is something wrong or not. I did the following, and all worked fine on my 10g instance. I had to assume some things, but I at least think I have the basic gist of your inquiry in this example. Run it/change it to match your situation, and post back when you can.
Thanks,
Ron
