Why would Google’s “Did You Mean” algorithm system suggest a grammatically incorrect alternative to my question? I did some research and found that basically–and according to Douglas Merrill, former CTO of Google–it is like this:
1) You write a (misspelled) word in Google.
2) You don’t find what you wanted (you don’t click on any results).
3) You realize you misspelled the word so you rewrite the word in the search box.
4) You find what you want (you click in the first links).
This pattern, multiplied millions of times, shows the most common misspells and the most “common” corrections.
This way Google can, almost instantaneously, offer spell correction in every language.
This also means if overnight everyone start to spell night as “nigth” Google would suggest that word instead.
