Remove query

We are using rt361

How can I permanently delete a search from RT System’s saved searches?

This is what I am doing now:

  1. Start at RT at a glance
  2. Click on Edit for the search I want to delete
  3. Click on You can also edit the predefined search itself: Search ->
  4. Click on Delete

But the search is still there.
Am I doing something wrong?
Do I need to manually do something in the database? I can see the
entries in the Attribute table but there is no disable field. Do I just
delete the entry?

Any help would be appreciated.
