"Google Inc. has been subpoenaed by the U.S. Justice Department to turn over a database of search terms as part of a government probe of online pornography but Google rejected the demand as overreaching by the government.

In a Wednesday filing in the U.S. District Court for the Northern District of California, the Justice Department demanded that Google provide all queries entered on the company's Web search system between June 1 and July 31 of last year.

The Justice Department includes a request for Google to produce a random sample of one million Web addresses, known as URLs."
