Searching in large PDF files. What technology to use?

python pdf elasticsearch search indexing

I made an applicant tracking system which has more than 20,000 CV and the best approach for you is ElasticSearch, Because:

very high performance
100% accuracy for searching
very easy to use with simplest APIs
easy to backup with replicas

And I recommend to use ElasticSearch amazon service ES.

And about UI framework I just use JavaScript with FineUploader what hepled me a lot with chunking and parallel upload.
