After months of speculation about what Amazon.com would

　　do with its mysterious search-engine company, A9, Web

　　surfers finally got their first taste on Apr. 14.

　　Yet despite of some intriguing new features not yet found 1.

　　on leading sites such as Google and Yahoo! , the site

　　(www.a9.com) -- still in test mode -- rises as many questions 2.

　　as it answers.

　　The biggest question remains is whether Amazon, 3.

　　through A9, would clash into Google more directly. 4.

　　Google itself is testing a search engine for products

　　called Froogle that's starting to appeal Web shoppers. 5.

　　At the same time, Amazon clearly isn't looking to limit A9's horizons.

　　How directly A9 eventually goes up against the reigned 6.

　　search champion, it faced lots of challenges. For one, 7.

　　it may run into some of the same privacy issues that

　　recently have plagued Google. A9's privacy policy points

　　out that information provided through entering search term 8.

　　or by signing into one's Amazon account could supply the company

　　with information that could personally identify the searcher.

　　Those may be somewhat less intrusive(打扰的，冒犯的) than 9.

　　Google's upcoming Gmail free e-mail offering, which could search

　　the contents of messages to pitch personalized ads. But comments

　　posted on some sites already indicate some people are

　　uncomfortable with Google's potential threats to privacy. 10.
