It's easy to do a search. First, look at the drop-down menu right below the text field. You'll find three options: "Search by Author," "Search by Title," and "Search by First Line." Simply select the option you want, then enter what you're looking for into the text field. Just hit "Submit" and off you go! In case it really could be easier than that, everything is done via fancy ajax, meaning this page never refreshes.
