I am using elastic App Search, and I want to index some PDF Documents with data such as title, writer, etc.
Is there any option for index them directly (I know FSCRAWLER for Elastic Search)??
My second option is to codify a Ruby program using gems that can make transform the pdf data in a Json document.
I think to use Apache tika but I do not know if there are better options for doing it.
Thank you for your help.
