How do I add a google web search to a web page?

How do I add a google web search to a web page?: Posted by drtao on March 7th, 2006; I would like to add a google search to a web page but don't want to add
a site search, can this be done?

Currently I have a google web search with a site search, but since
there is only one page on the web site it's kinda useless.

TIA
