I created a filter on a site where we have pdf files that are product details. These kinds of pdfs are linked to special acf posts called Sicherheitsdatenblätter.
When I search I would like it to search for names based on the name of the post and not the name of the pdf. When clicking on the searched pdf it should then open in a new page.
There is also a button option to load the further list of pdf’s, this should search the pdf’s in the list even if not yet opened.
