In my opinion, information can never be retrieved from a single source. It always pieced together from different sources by the person with a task at hand. Google is a tool which can let you jump to different pages quickly and let you develop insights into the data they offer and put together your own judgment. Most search engines used to rely on token matching semantics to retrieve results. This has widely changed in the last few years. The golden hammer today is user-data. Google receives millions of clicks a second. With this, it tones its indexes and cached results to provide "better results". So if many people think Wikipedia is their best answer for "mashed potatoes", you probably also do. I guess a single keyword search is not going to get anything sensible out. The answer lies in being able to interact with such systems and get what you want. Solving the search/retrieval with a single query is a very hard problem as it depends on the context of the user. Try searching for the word "Execute". Does it show pictures of a person being hung or a how-to for the first hello world program in a terminal?
