Abstract: A device implementing a system for determining an answer to a question includes a processor configured to receive a question from a client device, and send the question to a first information domain comprising plural search subdomains, each of the plural search subdomains being configured to provide a respective candidate answer to the question in a format that differs from those provided by the other search subdomains of the plural search subdomains. The processor is further configured to receive, in response to sending the question, the candidate answer from each of the plural search subdomains, and provide at least one of the candidate answers to the client device, for providing an answer to the question based on the at least one of the candidate answers.
