searchwp_pdf_spaces_to_content_percentage

A number of guards have been implemented in SearchWP’s parsing and indexing of PDFs. This hook allows you to better control whether SearchWP has detected a problem in parsing PDFs by setting an upper limit as to how much of the content is white space when compared to characters.

By default if more than 5% of the content is found to be white space, the PDF is considered to be problematic and SearchWP will skip it. You can control this threshold like so:

      
        <?php
      
        // Allow PDFs with up to 10% white space to be indexed.
      
        add_filter( 'searchwp_pdf_spaces_to_content_percentage', function( $percentage ) {
      
          return 10;
      
        } );
