Type "French Military Victories" in Google and click "I'm feeling lucky."

I saw the ABS thing. What's their relationship with Google? The "I'm feeling lucky" redirects to their site.
"I'm feeling lucky" just sends you to the top link of the search results. ABS has no relationship with google, they are just the highest ranked search result for the query.
Some of the most famous Google bombs are also expressions of political opinion (e.g. "liar" leading to Tony Blair or "miserable failure" leading to the White House's biography of George W. Bush).
On a related note, if you type in "search engine" into Google, google.com only comes up 6th. Weird.
What's a search engine?
