Welcome David

If you search for Thrive you will get many results, so yes, it works with it. For example:

https://support.searchandfilter.com/forums/topic/filter-on-thrive-theme-builder-post-grid/

But, it is easier for me to show you how over Skype.

Here is the ‘starter’ results.php for your Thrive theme:

<?php
/**
 * Search & Filter Pro 
 *
 * Sample Results Template
 * 
 * @package   Search_Filter
 * @author    Ross Morsali
 * @link      http://www.designsandcode.com/
 * @copyright 2015 Designs & Code
 * 
 * Note: these templates are not full page templates, rather 
 * just an encaspulation of the your results loop which should
 * be inserted in to other pages by using a shortcode - think 
 * of it as a template part
 * 
 * This template is an absolute base example showing you what
 * you can do, for more customisation see the WordPress docs 
 * and using template tags -
