Elastic Stack Elasticsearch

I implemented fscrawler, Tesseract with kibana, and elastic search for pdf, and it is possible to know if it is possible to some statistics in graphical charts (example: to know the occurrence of word in each pdf or image) is there any solution or tool that can perform that

You can enable fielddata on the content field and use Kibana to display a tag cloud on that field.

Note that it can use a lot of HEAP memory.

But that won't be per document.

I'm afraid I can't do that.
I'd first learn what elasticsearch and kibana are by following some guides/tutorials:
