Unlike the old/early days, contemporary search engines also no longer respect the quote-strings; the practice of keeping anything within quotes as 1 contiguous string, thus limiting the results to that one unique combination of letters and words, not counting "did you mean" suggestions.

Instead no matter what, everything you type in a search box these days returns hits upon each and every word as separate units regardless of if you try to limit the search to contiguous strings within quotations. IMO that is a huge step backward.
