Skip portfolio item page and go straight to content

Hi, Im using free version and I was wondering if theres a way to link results straight to documents instead of going to portfolio item page. I have lots of pdf′s files and my idea is after i get results from filtering just click on thumbnail and go straight to the pdf file, not the portfolio post. Can your please help me? Thanks in advance.

Kind regards

(i tried by changing ”#the_permalink#” to ”#the_content#” but did not work as i expected)
