merging node search (standard search) with directory search

Hello,

I installed the search files module and currently you can either search nodes with the standard Drupal search, or click on the "search in directories" tab and search for PDFs. I would like to merge the two into a single search and get a query result with both relevant nodes and relevant pdfs, a little bit like what the Google search does on websites. You might get a page for the first result and a PDF for the second element in the result list because of its relevancy.

Is there a way to do this with search files? Or is it something that would require development.

Thanks so much for your help and insights,
