Why does autocorrect in search engines almost never work correctly?

[genius]

Autocorrect or whatever it is called in search engine terms, starts guessing what I am typing, no matter how fast I type. I can type over 80wpm and it doesn't matter how fast you type; It seems to work better by typing slower. About 1 out of 4 times when I type a word in after another word with a space in the middle, my next word gets all it's letters changed to the same amount of spaces. Also when the search engine starts guessing, it slows down the search engine so much to the point you can barely type anything, each letter you type takes 2 or 3 seconds just to show up in the search box because it has slowed itself down so much from guessing things you probably weren't wanting to search for in the first place. Aside from that, you can spell a word or phrase right, and search for it, and the search engine will change what you put and search for that instead. It will then show you results for something you didn't even want to look for and say "Did you mean:" with your word or phrase that wasn't searched for at all. It seems to just be a way for the search engines to see what you are typing before you actually search for it, just to see what people might be searching for before they press enter or click search.
