Google currently does not allow outsiders to gain access to raw data because of privacy concerns. Searches are logged by time of day, originating I. P. address (information that can be used to link searches to a specific computer), and the sites on which the user clicked. People tell things to search engines that they would never talk about publicly - Viagra, pregnancy scares, fraud, face lifts. What is interesting in the aggregate can be seem an invasiion of privacy if narrowed to an individual.
