OCR'ing of PDFs is fiddly at the moment because of Tika, not Solr! We have an open ticket to make it "just work", but we aren't there yet (TIKA-2749).
You have to tell Tika how you want to process images from PDFs via the tika-config.xml file. You've seen this link in the links you mentioned: https://wiki.apache.org/tika/TikaOCR This one is key for PDFs: https://wiki.apache.org/tika/PDFParser%20%28Apache%20PDFBox%29#OCR On Fri, Nov 2, 2018 at 10:30 AM Furkan KAMACI <furkankam...@gmail.com> wrote: > > Hi All, > > I want to index images and pdf documents which have images into Solr.
