I don't understand why you would deploy something that looks like an information retrieval tool, but simply invents things when it doesn't know the answer.No one would design a database system that returned random data if a query failed to match any records. (Except perhaps in a specialized application such as a game).The argument “but it gets it right MOST of the time" cuts no ice. That actually makes it WORSE, because it's harder to tell when the robot is fabricating answers.5/
