Yahoo! recently claimed that their search engine index had grown to 20 billion items, over twice as large as Google's 8.1 billion. Quite the bragging rights that gave Yahoo!. An independent study however, by the NCSA, has found that while Yahoo!'s claims can't be verified, Google remains the search engine with the most. Consistently, Google kept returning more results, especially for obscure searches, which this study focused on. (Both Google and Yahoo! truncates results after 1,000 results, so the researchers decided to look at obsucure searches.) Yahoo! only returned 37.4% of the results that Google did.
