[edit] Google Custom Search

You can get to Google Custom Search by clicking the 'research' tab, then the 'Google Custom Search' tab.

Google Custom Search allows you to search across all of your resources using Google's Custom Search Engine. For more information on setting up Google Custom Search, see our Screen-by-Screen article on Google Custom Search or our Cookbook Recipe on Google Custom Search article.

To use Google Custom Search, enter your search term into the box, select the Custom Search you wish to use, and hit search. A window will pop up with your search results in it.
