I found a related post here but I'm still confused and not sure whether it's correct to use "How'd I come here?".
When search in google I got only about 11 results for "How'd I come here?", but I got about 200 results for "How did I come here?". Why is that? Because this I think "How'd I come here?" is not correct or not acceptable in correct English.
But looking at the other post I mentioned, it seems it's correct and common to say "How'd I come here?". Google doesn't agree with that. What am I missing?
