Are you intending to use the solution in production? If so, combining Tika and Tesseract on the same server could not be a good choice. Tika and Tesseract are heavy processing consumers, harming the main service on the solution, in your case, Solr service. I had the same situation here, and the combination Tika/Tesseract in the production server does not scale, once I have many text documents and images. An alternative is to use a microservice to text preprocessing and another one to OCR. You can take some ideas from https://github.com/tleyden/open-ocr . I have a separated Kubernetes cluster just for this, to extract and OCR text from binary documents. Now, I can scale to a world-class solution.
