Christine Poerschke commented on SOLR-8542:
-------------------------------------------
bq. ... Should we state explicitly that this example is not shipped in the
binary? ...
Done.
bq. ... Any reason why we don't out of curiosity ? ...
_As is_ the example folder content is not intended or suitable for production
use. The {{train_and_upload_demo_model.py}} script name intends to convey that
but inclusion of the folder in the release could be misunderstood to mean that
the example content is maintained and ready-to-use to the same extent as the
[solr/bin|https://github.com/apache/lucene-solr/tree/master/solr/bin] scripts.
bq. ... we need " all JARs under contrib/ltr/lib." . I don't see anything under
the binary. Is it safe to remove it? ...
Good catch! I was inspired by the "Installation" section of
https://cwiki.apache.org/confluence/display/solr/Result+Clustering and missed
that {{contrib/ltr/lib}} is empty. I just updated the documentation and created
SOLR-10451 for the techproducts solrconfig.xml update and to prune the empty
(except for README.txt) {{contrib/ltr}} folder out of the Solr binary release.
bq. ... BTW I love the documentation. ...
Thanks! :-)

> This is a ticket to integrate learning to rank machine learning models into
> Solr. Solr Learning to Rank (LTR) provides a way for you to extract features
> directly inside Solr for use in training a machine learned model. You can
> then deploy that model to Solr and use it to rerank your top X search
> results. This concept was previously [presented by the authors at Lucene/Solr
> Revolution
