Here's a skeletal program that uses Tika in a stand-alone client. Rip the RDBMS

Hi Martin,

I wrote a framework (https://github.com/nsoft/jesterj) that is meant to help 
with small to medium custom solutions It's not (yet) ready for cases where you 
need multiple machines feeding data, but so long as a single box can do the 
work it should be useful. It has a basic Tika stage which is ripe for 
enhancement. The example in the project uses Tika to extract text from 
Shakespeare's plays, though I'll admit that the Tika processor class it has not 
yet been given the full set of configuration options.  Fleshing that out is on 
the list of things to do and would be easy and welcome as a contribution 
(https://github.com/nsoft/jesterj/issues/74).

Usually, we just say to do a custom solution using SolrJ client to connect. 
This gives you maximum flexibility and allows to integrate Tika either inside 
your code or as a server. Latest Tika actually has some off-thread handling I 
believe, to make it safer to embed.

For DIH alternatives, if you want configuration over custom code, you could 
look at something like Apache NiFI. It can push data into Solr.
Obviously it is a bigger solution, but it is correspondingly more robust too.

   Alex.

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

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.

Hi again,

Is there anyone who has some experience of using Tesseract’s OCR module within 
Solr? The files I am trying to read into Solr is Danish Tiff documents.

Hi,

I have been trying to use Tesseract through the data-import-handler in Solr and 
it actually works very well – with English. As the documents are  in Danish, I 
need to change the language setting in Tesseract to Danish as well, is that 
possible from Solr?

I was using the update/extract-handler to import single files into Solr, and it 
worked for a single file, how would I implement several files from a 
file-system?

Here is the request-handler I used:



  false
  ignored_
  true
