What is the difference between "Did you find?" and "Have you found?"
When should I use the first sentence, and when the second one?
Did you find is the simple past and indicates that you are no longer looking for it.
Have you found is the present perfect and indicates a link with the present, specifically, that you could still be looking for it.
