title: Multiple file types search using Google Custom Search API
body: <p>I need to get Google search results for particular filetypes.
  For example, in browser I would directly google search for "<strong>hyperloop filetype:pdf</strong>" and it will list out PDF files for "Hyperloop".
  For this, my Google Custom Search request URI will be <a href="https://www.googleapis.com/customsearch/v1?key=MY_KEY&amp;cx=MY_UNIQUE_ID&amp;q=hyperloop&amp;fileType=pdf" rel="nofollow">https://www.googleapis.com/customsearch/v1?key=MY_KEY&amp;cx=MY_UNIQUE_ID&amp;q=hyperloop&amp;fileType=pdf</a></p>
  
  <p>However, currently I would like to get search results for "hyperloop" of filetypes .ppt or .doc.
  In browser, I would achieve this by googling "<strong>hyperloop filetype:ppt OR filetype:doc</strong>".</p>
  
  <p>What will be my Search request URI equivalent for this query?
  I could not find anything related to querying using multiple values for a single parameter in <a href="https://developers.google.com/custom-search/v1/using_rest" rel="nofollow">Google Custom Search Documentation</a>.</p>
