Minimum Characters For Search In Version 4.1.3

We are running a large database using cs-cart, over 250000 products. Most functions perform good but when someone clicks on search button with blank input , cs-cart by default lists all the products. This causes very high load on server. Is it possible to stop search being performed unless there are minimum 3 characters in input box for default cs-cart search?

Any suggestions.

It used to be that way… Post it in bugtracker.

No this feature has always been lacking in If you check, with billions of products in their database and try to search for blank, you are redirected back to home page. I think can also achieve that functionality also by making the default search input as a required field. I do not know why search field is not a required field!!!.
