Search Results Page Redirecting to Index when adding product to Cart

Hello,

I've searched the forums but have not found an answer to the problem I'm having. I've set the admin up so that:

Configuration > My Store > Display Cart After Adding Product = False

so that my site will not redirect to the shopping cart when a user adds product to their cart. This works great everywhere except the Search Results Pages.

Problem:
When a user searches and adds a product to the cart, they are being redirected to the home page (index) rather than their search results pages. This presents a bad user experience, and I'm trying to have the search results pages work like the rest of the site.

Running version: v1.3.9h

In short, the URLs after adding to cart look like:
/index.php?main_page=index

instead of:
/index.php?main_page=advanced_search_result

Would love any help anyone can give on this topic/problem.

Thank you!
