I have more information that might be helpful. My programmer said:
By the way, this is the filter I was trying to use. https://knowledgebase.ajaxsearchpro.com/hooks/filters/search-results/asp_attachment_results
But when I used it in the code snippet plugin the results would not change. I tried changing the title and link, but nothing changed. However when I returned a blank in the function the search results page would show that no results were found, so that was strange.
Thank you,
Kimi
