Solr Cell examples in official docs not working for me?

[ufuk yılmaz <uy...@vivaldi.net.INVALID>]

Today I tried to index some pdf files and see how that goes.

After a few hours of unsuccessful attempts using SolrCloud docker image etc. I decided I should follow the exact path in the documentation first.

I downloaded Solr 8.11 archive from: https://www.apache.org/dyn/closer.lua/lucene/solr/8.11.2/solr-8.11.2.zip?action=download

I extracted the archive to a folder, then run the command in docs: https://solr.apache.org/guide/8_11/uploading-data-with-solr-cell-using-apache-tika.html

bin/solr -e schemaless

It started without problem and created a core named “gettingstarted” everything works!

Then I tried out the command in docs:
curl 'http://localhost:8983/solr/gettingstarted/update/extract?literal.id=doc1&commit=true' -F "myfile=@example/exampledocs/solr-word.pdf"

It gives me 404 error. I was also getting 404 with various other methods I tried today. It seems the “schemaless” example doesn’t configure ExtractingRequestHandler in solrconfig.xml at all for me.

Am I doing something wrong?

Solr 8.x is close to dead.  It is in maintenance mode, which means that 
major bugs and security issues are all that will be fixed.  When 10.0.0 
gets released, 8.x will be entirely end of life and 9.x will move to 
maintenance mode.  Releases are never scheduled in advance, so I do not 
know when 10.0.0 will be released.

The instructions in the documentation appear to be incorrect for 8.11. 
The schemaless example does not have the correct handler in its config 
for SolrCell.

You should be using 9.x.  The instructions in the latest ref guide seem 
to be complete.  Those instructions are not going to be usable with 8.x 
because they use functionality only found in 9.x.

Using SolrCell in production is strongly discouraged.  Tika can be very 
unstable.  It is known to consume large amounts of memory and even 
crash.  If this kind of problem occurs when Tika is running inside Solr, 
that problem will affect Solr too.  It is better to write a separate 
program that runs Tika and indexes the data gathered to Solr ... a 
program with infrastructure that can recover from misbehavior like crashing.

This is stated in the ref guide:
