A user wishes to view a record, such as one that includes a person's medical history, located in a record storage area. In order to prevent the user from viewing records other than the specific record in which the user is interested, a record selection manager iteratively requests attribute information from the user to disambiguate which record to provide until the record selection manager identifies a reduction completion result, which the record selection manager then provides to the user. Using the invention described herein, the record selection manager conceals records included in the records storage area until it identifies a reduction completion result and, at that point, the record selection manager provides only the reduction completion result to the user to view.
