Varun Thacker commented on SOLR-8542:
-------------------------------------
Oh I see what happened.
On https://cwiki.apache.org/confluence/display/solr/Learning+To+Rank I was
reading the "Training example" section which took me to
https://github.com/apache/lucene-solr/tree/releases/lucene-solr/6.4.0/solr/contrib/ltr/example
and then I was like why isn't {{contrib/ltr/example/config.json}} there
So I have a few questions:
1. Should we state explicitly that this example is not shipped in the binary?
Any reason why we don't out of curiosity ?
2. The "Installation" section of
https://cwiki.apache.org/confluence/display/solr/Learning+To+Rank states that
we need " all JARs under contrib/ltr/lib." . I don't see anything under the
binary. Is it safe to remove it?
BTW I love the documentation. Very thorough

> 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
