Hey,
thanks for reaching out! Unfortunately I must inform you that although our plugin can search for attachments on your blog, it cannot index & search through your PDF files.
But we still believe there’s a way to get your PDF’s content searchable though — try to copy & paste the content of your PDF file into the custom field box, when editing that particular blog post where you attached that file. This way, our plugin should be able to search for/through the content of your file via the custom field option. We would really love to hear about the results, if you choose to give it a try.
As far as we have been able to test it on our end — it works.
The other option is to install the following plugin, which certainly does claim that it can index your PDF files and make them searchable. Here’s the link: https://searchwp.com/
Hope this helps, take care and have a nice day,
Petra
