I just checked again. Here's what I get:

- no results with or without quotes:

    No results containing all your search terms were found.

- few results with quotes, not more without quotes:

    Your search did not match any documents.

    It looks like there aren't many great matches for your search
    Tip: Try using words that might appear on the page you’re looking
    for. For example, "cake recipes" instead of "how to make a cake."

- no results with quotes, but results without quotes: Google says that the search with quotes didn't find anything, and that they searched without quotes instead.

I have yet to find any instance where Google corrects the inside of quotes without any warning.
