Hi Charlie, Thanks for the reply. You're right. I haven't got my hands dirty with solr yet. I am not from an IT background and learnt everything I know through lots of reading online. However, all the documentation on solr assumes that the reader has advanced IT knowledge. In fact, it took me a week to learn to install and configure solr index to work with WordPress.
Getting solr to ocr appears to be beyond me. And I can't code. *Would you consider setting this up for me for a fee? * And also with a step by step guide for dummies in case I intend to upgrade in the future. I also noticed that Tika 1.14 is capable of ocr by itself. I would be okay with a setup of solr using Tika 1.14 to ocr the PDF if that is possible.

One way to use Tesseract would be via Apache Tika https://wiki.apache.org/tika/TikaOCR which is an awesome library for extracting plain text from many different document formats and types. There's a direct way to use Tesseract from within Solr (the ExtractingRequestHandler https://lucene.apache.org/solr /guide/6_6/uploading-data-with-solr-cell-using-apache-tika. html#uploading-data-with-solr-cell-using-apache-tika) but we don't generally recommend this, as dodgy files can sometimes eat all your resources during parsing and if Tika dies then so does Solr. We usually process the files externally and the feed them to Solr using its HTTP API. Here's one way to do it - a simple server wrapper around Tika https://github.com/mattflax/dropwizard-tika-server written by my colleague Matt Pearce. So you're going to need to do some coding I think - Python would be a good choice - to feed your source files to Tika for OCR and extraction, and then the resulting text to Solr for indexing.
