I get quite different query parameters. For example, I just searched for [foo] from the Firefox search box, and got these:

   google.com/search
   ?q=foo
   &start=0
   &ie=utf-8
   &oe=utf-8
   &client=firefox-a
   &rls=org.mozilla:en-US:official

...not one of which is listed in the blog post. In particular, I've always had "q" for the query string, and not "as_q".

Odd, I must have missed "gl". I'll look into it and add it.

I assume the "as_q" stands for "advanced search". You raise a good point though. I'll go though and add the parameters from Firefox and Internet Explorer.

Yeah, AFAIK some of the "as_"-prefixed parameters have their unprefixed equivalents. "as_q" and "q" is one of them.

"as_sitesearch" and "sitesearch" have the same meaning too, but they differ slightly in implementation details. With "as_" – the "site:example.com" is automatically added to your query box, whereas the unprefixed one doesn't do that. Additionally, "as_dt" only affects the prefixed "as_sitesearch", not the other one. Compare these URLs to see what I mean:
google.com/search?q=google& ...
google.com/search?q=google& ...
google.com/search?q=google& ...

BTW, some of the parameters are not well documented on Google Search help pages, but they are quite similar to the parameters from Google Search Appliance, which are documented here:
code.google.com/enterprise/doc ...

Thanks, I'll look into that.

I am also missing the parameter for faces-part for the imagessearch (was in the news recently)

&imgtype=face

Seems Google Image search has an advanced search as well.
