Also when testing, if you know a piece of information exists in a website, but the information doesn't show up when you run the query, you don't have the tools to steer the engine to work more effectively. In a real scenario you don't know what the engine missed but it'd be cool to steer the engine in different ways to see how that changes the end result. For example, if you're planning a trip to japan, maybe you want the AI to only be shown a certain percentage of categories (nature, night life, or places too), alongside controlling how much you want to spend time crawling, maybe finding more niche information or more related information.
