We have a new test box and I like to put people search in the main search drop down. How is it done? I tried googling and it talks about setting up user profile which I already did. and sync is working and I now have population in user profile. Please suggest.
Create a search center in the root site collection.
From the site collection in question, navigate to Site Settings, Search Settings (under Site Collection Administration). Or navigate to http://yoursitename/_layouts/enhancedSearch.aspx Here you want to choose 'Enable custom scopes' and enter your search center address (i.e. /searchcenter/pages).
You can then decide what scopes to show with the Site Collection Search Dropdown mode choice on that same screen.
