Site-level Search Box settings are similar to collection-level settings, as described above, except that they inherit both from the farm level and from the parent site.
To make Search Box settings for a given site, do the following:
1. Log onto SharePoint and navigate to the appropriate site.
2. Select Site Actions > Site Settings > Modify All Site Settings. The Site Settings page opens.
3. Under the Site Administration heading, click on the Ontolica search box scopes link.
You now see the Search Box scopes that apply at the site you selected. This includes a list of all Search Box scope configurations and indicates which of these are inherited and/or customized. Use the controls here to configure which scopes will be available at the current site and to configure each available scope. Use the Settings link to make general Search Box settings for this site.
