Mercury News has details of a San Francisco judge's decision that Google should give the DoJ some details on its search engine, but
is not required to turn over records to the government. From the article:
"McElvain emphasized the study would be more meaningful if it included search requests processed by Google, which by some estimates fields nearly half of all online queries in the United States. Ware concurred with the Justice Department on that point, writing in his order that 'the government's study may be significantly hampered if it did not have access to some information from the most often used search engine.' But Ware said the government didn't clearly explain why it needed a list of search requests to conduct its study, prompting him to conclude the Web site addresses would be adequate." Reaction to the news is available on the Google Blog.
