Marissa Mayer who is Google's VP for search products and user experience said that "Google had invested in automatic translation as a way to improve search results across various languages" and Google was moving " towards integrating all of its different search engines, including its Google Book Search and Google Patent Search, to produce comprehensive results for the same search".

She also says that "We're just getting started with universal search, there are a lot of issues to overcome here." via InfoWorld

One key thing would be the user interface to present these results in a way that it's going to make sense to the user and bring the "real meaning out of the content".
