Google and Microsoft edge has ( Auto ) spell check on their web search engines
Yahoo dose not! Why?

I use yahoo all the time, but I'M not a good speller.
When I'M having trouble searching for something on the yahoo because of spelling
I have to close yahoo and search from Google

Yahoo needs to get with modern technology, and at least have spell check
Yahoo is falling way behind all the other search engines!

I use yahoo all the time #1 because i love Yahoo news home page and i do my web searches on that sight
but yahoo dont have auto spell check! WHY ?
