=item C<search()>
Creates a query string, then passes the appropriate form fields to the Pearson
Education server.
The returned page should be the correct catalog page for that ISBN. If not the
function returns zero and allows the next driver in the chain to have a go. If
a valid page is returned, the following fields are returned via the book hash:
isbn (now returns isbn13)
isbn10
isbn13
ean13 (industry name)
author
title
book_link
image_link
description
pubdate
publisher
binding (if known)
pages (if known)
weight (if known) (in grammes)
width (if known) (in millimetres)
height (if known) (in millimetres)
The book_link and image_link refer back to the Pearson Education UK website.
