I must have missed the line "No results found" and the disclosure that Google has, by default, gone ahead and performed a "fallback query" without the quotes. Perhaps that is the goal. That I, the user, will not notice. If I wanted the fallback query's results then I would not have used quotes. This appears to be another another example of Google second-guessing the user. Perhaps they assume that the user who searches for an exact string with quotes would, in most cases, try the search again without the quotes if there are no results found.
