Hi Alexandre, Thanks for your reply.
Yes right now it is just for testing the possibilities of Solr and Tesseract. I will take a look at the Tika documentation to see if I can make it work. You said that DIH are not recommended for production usage, what is the recommended method(s) to upload data to a Solr instance? Best regards Martin Frank Hansen -----Oprindelig meddelelse----- Fra: Alexandre Rafalovitch <arafa...@gmail.com> Sendt: 21. oktober 2018 16:26 Til: solr-user <solr-user@lucene.apache.org> Emne: Re: Tesseract language There is a couple of things mixed in here: 1) Extract handler is not recommended for production usage. It is great for a quick test, just like you did it, but going to production, running it externally is better. Tika - especially with large files can use up a lot of memory and trip up the Solr instance it is running within. 2) If you are still just testing, you can configure Tika within Solr but specifying parseContent.config file as shown at the link and described further down in the same document: https://lucene.apache.org/solr/guide/7_5/uploading-data-with-solr-cell-using-apache-tika.html#configuring-the-solr-extractingrequesthandler You still need to check with Tika documentation with Tesseract can take its configuration from the parseContext file. 3) If you are still testing with multiple files, Data Import Handler can iterate through files and then - as a nested entity - feed it to Tika processor for further extraction. I think one of the examples shows that. However, I am not sure you can pass parseContext that way and DIH is also not recommended for production. I hope this helps, Alex.
