Hello
Thanks for your remark.
Maybe it would be relevant to improve the documentation page. I had
suggested a few clarifications and the changes were reviewed and
accepted : see this thread
https://mail-archives.apache.org/mod_mbox/jena-users/201901.mbox/browser
This is what Ajs6f said about contributing :
"you needn't be a committer or have any other official role to improve
that page. Just use the link in the upper right to submit your suggested
changes, and I promise to review/commit them! (Probably with some help
from Chris or Osma, who know the text-indexing machinery much much
better than do I.)".

Hello,
According to turtle syntax document(https://www.w3.org/TR/turtle)
“:My_index_ES” with prefix
“@prefix :
<http://localhost/jena_example/#<http://localhost/jena_example/>> .” will be
parsed as
“<http://localhost/jena_example/#My_index_ES>”
But ,
Relative IRIs like <#indexES> are resolved relative to the current base IRI. A new
base IRI can be defined using the '@base' or 'BASE' directive. If <#indexES> is used,
it should be defined as follow:
@base <http://localhost/jena_example/#> .
<#indexES> a text:TextIndexES ;

Subject: Re: Can't use ES in jena's text_dataset
Hello
I've spent hours with a similar problem (with Lucene, not ES).
Maybe you should provide a fixed uri for your index ?
:My_index_ES instead of <#indexES>
It worked for me.
I wrote a small tuto where you can find working examples of assembler
files and text queries (for Lucene)
https://sourceforge.net/projects/ffl-misc/files/TUTORIEL_Fuseki_BnF.pdf
The tuto is in French but you will find code samples and commands.

Actually, even using text-config-es.ttl in jena-text-es module wouldn't work...

Is there anything wrong in my code?
