A scope group’s settings include its ID, name, description. Once a group is created, you can no longer change its ID, but you can edit its name and description at any site level as follows:
1. Go to the Search Scopes page for the site level at which you want to edit the scope group as described above under “Creating a New Scope Group”.
2. Click on the target group name and select Edit Group from the action menu. A pop-up dialog for editing the group opens.
Make the following settings:
Name: Enter a name for the group as it should be presented on the Search Scopes page.
Description: Enter a short description for the group. This will help remind yourself and other administrators about the intended purpose of the group.
3. Click OK to close the Edit Search Scope Group page and store your settings.
Note that if you edit the name and/or description of an inherited scope group, then your settings will apply at the current site level (and below) only. Furthermore, these settings will no longer track changes made at higher levels in the SharePoint hierarchy.
