Oracle Text Query taking too long

Question

When we run a query:
select docid from Tbl1 where contains(doc,'queryterm',1)>0;
on 2 million docs it runs in <2 seconds
When we run an insert into another table based on a search:
insert into Tbl2 (col1,col2) select 10,col2 from Tbl1 where rowid<2000; (10 in the select statement is a constant)
it runs in <2 seconds
Here's the kicker:
insert into Tbl2 (col1,col2) select col1,col2 from Tbl1 where contains(doc,'queryterm',1)>0;
it runs in 60 seconds and produces ~2k rows
Is there any hint that we can use to fix this?
TIA!

Answer 1

We've looked hard at the performance notes for Oracle Text, the Application guide and the FAQ on it.
We've dropped the index on the table being inserted, turn off logging and used the Parallel hint on the insert. There is still a bit of a disconnect between insert speed, select speed and both together. The index was built using the parallel option so the queries should be parallel if I understand the performance hints correctly.
