If you just omit it, the fourth parameter will then become the third
parameter and there will be no fourth parameter. That isn't what you
want. The best way to do this in "short form" is to use the url(...)
style of url patterns. To wit:
url(r'^search/$', 'books.views.search', name='search_page'),
There's no real difference between this and the tuple form (internally,
Django converts the tuple form into a url(...) form), but the above
version is a proper Python function call, so you can use keyword
arguments. The fourth argument is called "name", so you can specify it
without needing to give the third argument.

That is indeed correct. If you had any arguments in the search pattern,
say,
url(r'^search2/(\d+)/$', 'books.view.search',
name='search_page2'),
you could write
reverse('search_page2', args=[42])
to reverse that call. The reverse() call takes "args" and "kwargs"
parameters and the former should be a list or a tuple (the kwargs
parameters would be a dictionary). You must call them "args" and
"kwargs" and not use positional parameters, since, for historical
reasons, the second argument of reverse() is something else that you
don't use here.
