Its more than that. It takes the input and tries to interpret the bad grammar and sentences into search terms and finds link the correlate the highest to its interpretation and then gives back the response that summarizes the results with good grammar and plausible sentences. Again this is why I stress that you have to evaluate its response and sources. The sources are the real value in any query. Im actually not sure how much the chatbots give sources by default though as I know I have not gotten them and then asked for them and now I get them as a matter of course so im not sure if it learns that I want them or if they did a change to provide them when they had not before.
