This advertisement by Google says these:
Google learns from typos and spelling mistakes we all make when searching to help give you
quicker and more accurate search results. So if you type ‘grizzly pears’, we can guess that you
probably meant ‘grizzly bears’.
Goggle does not have a degree in English. We can do this because over the years we’ve
studied how people search and learned what the most common errors are. So it’s good to
know that all those little mistakes aren’t made in vain.
