Does it work for this PDF document?

After importing that file, I can search on terms like freelancing, staffing, etc., which are in the document text but not the title.
If you select the parent item of the PDF file you imported and display the Item Text column (F9), that column will show the text (if any) that UR found in the document.
Note that some PDF files aren't parseable for text content. One PDF text parser vendor indicated, "Some PDFs will simply never parse the way you would expect them to for various reasons. There is NO PDF to text converter in the world that can work with every PDF file ever created. Even Adobe itself cannot convert all PDFs to text properly." The PDF parser we use works with most files we have tested, but I believe that if the text in the PDF file is encrypted or stored in a non-standard format, most tools can't parse text from them.
