Hi,
Solr 6.4 enabled support for LTR machine learning model with the goal of improved search relevancy . I was wondering if elasticsearch or prelert will support this in future?
" Machine Learning:
Configurable Learning-To-Rank (LTR) support: upload feature definitions, extract feature values, upload your own machine learnt models and use them to rerank search results. " - from http://lucene.apache.org/solr/news.html

I only took a very quick glance at the above link, and I do not think you will find this exact feature in Elasticsearch, but you should take a look at others which may offer ways to implement similar functionality.
You might want to take a look at the rescore query as well as in this work in progress branch (which is not yet released) called rank-eval
