Organize a quick search by content in pdf documents?

Question

Text recognising

Greetings,

there is a fairly large amount of pdf documents (50gb), you need to organize a search for their contents, tell me how to do this as simply and quickly as possible (requires a temporary solution without using ELK, etc.)?

What options do I see:
1. parse in python and save to the database, and already search there, the difficulty is that pdf is not so easy to parse as html, j son, xml

2. find some miracle utility that recognizes text and based on it, it will create a json / xml object and save it, and then search through these files ...

I will be any ideas and suggestions, my goal is simply to find pdf files in which they occur by keywords.

Answer 1

docfetcher.sourceforge.net/en/index.html
and other desktop search

Answer 2

If you do it yourself, then with the Solr full-text engine. It already includes a module for processing PDF documents and has its own HTTP API for requests. You need to write your own client program.
Or take ready-made software, as Dimonchik suggested .
