How can we view the changes from the product search results without refreshing the entire site cache?

When you are making changes during the day, but you don't want to clear the entire site cache, you can:

Add this to the URL: "?no_cache=true"

 
Example: "/product-category-group/camping-gear?no_cache=true"

If you are logged in as an administrator, there is an option from the search results page that will run it automatically. Look for the Refresh icon next to the filter options.
