WASHINGTON (Reuters) - DuckDuckGo, which has long complained that Google's tactics have made it too tough to get people to use their search engine on a mobile phone, will be one of many rivals to the online search giant eyeing a once-in-a-generation antitrust trial set to begin Tuesday.

The United States will argue Google didn't play by the rules in its efforts to dominate online search in a trial seen as a battle for the soul of the Internet.
