Views proximity search by postal code show all when empty I'm using proximity search in views 3.

The proximity search is by Postal Code.

When first loading the view page, it's showing all result.
In my case this is not good because the postal code is required for filtering.

My question is.

Is there a way to not showing all the result when postal code search field is empty.

Here is a screen shot of my views Criteria.

Thanks a lot
In the settings for the exposed search field, you should be able to change the behaviour: 
On Empty input, Show None.  Show All is set by default
