Shawn Heisey commented on SOLR-8542:
------------------------------------
I personally use 80 columns for files like README.txt, but from other people's
additions to CHANGES.txt, I know that others are using more. I am frequently
viewing text files like this in ssh or on terminals, so I find lines longer
than 80 characters to be annoying. For source code, I edit in an IDE more
often than with vi, so longer lines are not really a problem there.
> Integrate Learning to Rank into Solr

> Key: SOLR-8542
> URL: https://issues.apache.org/jira/browse/SOLR-8542
> Project: Solr
> Issue Type: New Feature
> Reporter: Joshua Pantony
> Assignee: Christine Poerschke
> Priority: Minor
> Attachments: README.md, SOLR-8542-branch_5x.patch,

> 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 2015 (
> http://www.slideshare.net/lucidworks/learning-to-rank-in-solr-presented-by-michael-nilsson-diego-ceccarelli-bloomberg-lp
> ).
> The attached code was jointly worked on by Joshua Pantony, Michael Nilsson,
> and Diego Ceccarelli.
> Any chance this could make it into a 5x release? We've also attached
> documentation as a github MD file, but are happy to convert to a desired
> format.
