Hello, can you give a hint what are those commercial libraries that would do the job? We need to index MSG files and OCR attachments within MSG. Tesseract can not do this, and I'm having hard time to find the solution. Thank you! -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: Using Tesseract OCR to extract PDF files in EML file attachment
Tesseract prolly knows nothing of the EML format. Your scripts could pull EML's apart.

Using Tesseract OCR to extract PDF files in EML file attachment
Hi, Currently, I am able to extract scanned PDF images and index them to Solr using Tesseract OCR, although the speed is very slow. However, for EML files with PDF attachments that consist of scanned images, the Tesseract OCR is not able to extract the text from those PDF attachments. Can we use the same method for EML files? Or what are the suggestions that we can do to extract those attachments? I'm using Solr 6.5.0 Regards, Edwin
