You have to look at it as a contractor. If you tell a contractor to "build me X" then you might get anything back with a high probability of getting something common but outdated. You have to write a specification for it with all of the constraints and preferences you have. Works well if you know the domain, if you're using it for something you don't know much about then you have to do more of the legwork yourself but at least it will give you a starting point that can inform your research.
