How to search Google for <meta name=“author”>

问题:

Is it possible to search Google for all sites built by a specific author declared by a meta author tag?

eg http://www.google.com.au/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=v6J&q=%3Cmeta+name%3D%22author%22+content%3D%22Fred+Smith%22%3E&btnG=Search&meta=

Looks like the answer is no: "Google, Yahoo, and MSN do not index the <meta> author tag." (source)
