Include search consistently

It's possible to go to, say, en.wikipedia.org/?search=foobarbazqux
or even en.wikipedia.org/wiki/an_article?search=foobarbazqux, because
MediaWiki is trying to kill me. Search pages are manually-accessed
HTML pages, and it's looking a lot like the iOS search
includes this structure. So, this patch includes them explicitly.
