I am trying to implement LTR (Learning to Rank) with a machine learning model. However, for some reason, the training with the judgment list is not succeeding. The LTR is not respecting my judgment list configuration with the defined weights.
Therefore, I would like to switch to implementing LTR via plugin. However, I would like to know if Elasticsearch version 8.15 supports the plugin.
If yes, I would also like to know how long the plugin will be supported and when it will transition definitively to the new machine learning-based implementation.
