Google Site Search trial.
Both annexe and main sites are searched and with no ads being displayed either. There is no charge for its use and there is unlimited usage too. The top bar works in the same way as standard Google search and presents the results in the same page.
Other features are that image search works too - see the Image tab at the top of each results page as are the contents of pdfs.
The second line shows the same search bar but occupying half the page width using a space on the left.
The third line has width set to 50% and the fourth one has width set to 300px
