Greetings!

I'd like to create redirect like http://site.com/? to http://site.com (http://site.com/? can contain anything after ?: e.g. http://site.com/?iwjekjwbefkjwe).

I've added string

rewrite /? http://site.com permanent;

to nginx config but without any success.
If I am adding string with another symbol different from question mark such as "- "

rewrite /- http://site.com permanent;

it works. How question mark could be used for this situation?
