I'm not a native English speaker, so whenever I type a sentence I always wonder if it is correct or informal use. My current approach is to input the sentence in Google Search and see how many results there are.
For example, if I'm wondering whether it is correct to write "have a question for my friend" or "have a question to my friend", I can easily determine this with Google by doing a search (note the quotes).
However this is quite inconvenient. So, how can I find out how many results there are from Google Search, instantly for whatever I type? Getting the autocorrections would also be nice…
