Ruby Forum Ferret > How to index PDF

Hello,

I'm actually trying to index PDF without success.
Anyone could explain how does it works ?

Thank you.

You must parse the PDF into pure text using some libs

i use the command line tool "pdftotext" for this which i put into 
lib/bin inside my app.

add a method to your model and add id to your indexed fields

e.g.

def text
  path = 'path/to/your/file.pdf'
  text = `#{RAILS_ROOT}/lib/bin/pdftotext -q \"#{path}\" -`
end
