You can get the extension from your account.

The Search & Filter – Divi Extension allows for integration between the Divi Modules and Search & Filter.

With this extension, Search & Filter will now be able to directly integrate with the following Divi modules:

• Blog
• Shop
• Portfolio
• Archives

Integrating with the Blog/Portfolio/Shop Modules

1. Add the desired module to your page
2. In content -> Scroll down underneath the options, and choose  Yes for Link with a Search & Filter Form
3. Then choose the Search & Filter Query you want to connect with
   
4. In your Search Form, make sure display method is set to Divi Blog / Porfolio Module or Divi Shop Module
5. Ensure you set the results URL to your page with the module, and enable Ajax without having to configure the settings
   

Theme Builder – Post Archive & Products Archive

The theme builder uses the exact same modules as above, so you can setup in the same way.

Alternatively, in your search form you can choose Post Type Archive or WooCommerce Shop for your display method.
