Folders search scope - i don't want

Dear KM friends,

Clicking on Show Options link of search window gives list of choices user can enter/select to do searching. right?

In that there two Search Scopes: 1. Index Groups and 2. Folders (and Subfolders).

Now requirment is, i want to avoid Folders (and Subfolders) scope, i want my clients should do searching only in Indexes given.

Any fruits?

plz reply me
