A system and a method are disclosed for performing a search with the assistance of a computer. The system may assign a unique identifier to a user, to a query submitted to the system by the user, to a human searcher that may respond to the query, and to a result produced by a human searcher in response to the query. These unique identifiers may be stored in a database, and associated with one another. The system may receive a query from the user during a first communication session, and present the query to the searcher to perform a search responsive to the query.
